the service `user@0.service` fails in system vms and virtual routers
This PR removes a change to fix memory leak of SSH connections in the systemvm templates with old linux kernel.
This PR fixes#6702
The service conntrackd will be started by the script /opt/cloud/bin/cs/CsRedundant.py, therefore add it to disabled_svcs so it is not started automatically when VR is started.
Fixes#6873
When the management server is in a different subnet than the pod in which a VPC VR is deployed, an ip route must be added just after creation of eth0 to allow the connectivity between the VR and the management server.

This PR fixes that the /etc/network/interfaces is misconfigured in VPC VR startup, which causes VPC VR to be stuck for 1 minute and continue working.
The issue is because ifup eth0 and ifdown eth0 do not work when /etc/network/interfaces is not correct in VPC VR.
This PR creates a new API createConsoleAccess to create VM console URL allowing it to connect using other UI implementations. To avoid reply attacks, the console access is enhanced to use a one time token per session
New configuration added:
consoleproxy.extra.security.validation.enabled: Enable/disable extra security validation for console proxy using a token
Documentation PR: apache/cloudstack-documentation#284
Adds option to provide custom DNS servers for isolated network, shared network and VPC tier.
New API parameters added in createNetwork API along with the corresponding response parameters.

* This PR/commit comprises of the following:
- Support to fallback on the older systemVM template in case of no change in template across ACS versions
- Update core user to cloud in CKS
- Display details of accessing CKS nodes in the UI - K8s Access tab
- Update systemvm template from debian 11 to debian 11.2
- Update letsencrypt cert
- Remove docker dependency as from ACS 4.16 onward k8s has deprecated support for docker - use containerd as container runtime
* support for private registry - containerd
* Enable updating template type (only) for system owned templates via UI
* edit indents
* Address comments and move cmd from patch file to cloud-init runcmd
* temporary change
* update k8s test to use k8s version 1.21.5 (instead of 1.21.3 - due to https://github.com/kubernetes/kubernetes/pull/104530)
* support for private registry - containerd
* Enable updating template type (only) for system owned templates via UI
* smooth upgrade of cks clusters
* update pom file with temp download.cloudstack.org testing links
* fix pom
* add cgroup config for containerd
* add systemd config for kubelet
* add additional info during image registry config
* update to official links
* Change logrotate interval to hourly
The logrotate config says interval as hourly but it relies
on timer service to be invoked but in timer the frequency
is mentioned as 12h. So it wont be invoked every hour.
So change the frequency to hourly
* Add change to vpc router
* vpc: fix ips on wrong interfaces after rebooting vpc vrs
* #4467: Rename to updateNicWithDeviceId
* CLSTACK-8923 vr: Force a restart of keepalived if conntrackd is not running or configuration has changed
When we create a vm in the network with redundant VRs, the lease file in the vm (for example /var/lib/dhcp/dhclient.eth0.leases) shows the dhcp-server-identifier is the guest ip (not vip/gateway) of master VR. That's the ip ipaddress where the vm fetch password and metadata from.
if we stop the master VR (then backup will be master) or restart the network with cleanup (VRs will be created), the guest ip of master VR changes so vm are not able to get metadata/ssh-key using the ips in dhcp lease file.
Setting up metadata/password/dhcp server on gateway instead of guest IP in redundant VRs will fix the issues.

In order to reduce memory footprint and improve boot speed/predictability.
The following changes have been made:
- add vm.min_free_kbytes to sysctl
- periodically clear disk cache (depending on memory size)
- only start guest services specific to hypervisor
- use systemvm code to determine hypervisor type (not systemd)
- start cloud service at end of post init rather than through systemd
- reduce initial threads started for httpd
- fix vmtools config file
Fixes#3039

On first startup, the management server creates and saves a random
ssh keypair using ssh-keygen in the database. The command does
not specify keys in PEM format which is not the default as generated
by latest ssh-keygen tool.
The systemvmtemplate always needs re-building whenever there is a change
in the cloud-early-config file. This also tries to fix that by introducing a
stage 2 bootstrap.sh where the changes specific to hypervisor detection
etc are refactored/moved. The initial cloud-early-config only patches
before the other scripts are called.

This introduces a new patching script for patching systemvms on KVM
using qemu-guest-agent that runs inside the systemvm on startup. This
also removes the vport device which was previously used by the legacy
patching script and instead uses the modern and new uniform guest
agent vport for host-guest communication.
Also updates the sytemvmtemplate build config to use the latest Debian
9.9.0 iso.

This tries to provide a threshold based fix for #2873 where swappinness of VR is not used until last resort. By limiting swappiness unless actually needed, the VR system degradation can be avoided for most cases. The other change is around not starting baremetal-vr by default on all VRs, according to the spec https://cwiki.apache.org/confluence/display/CLOUDSTACK/Baremetal+Advanced+Networking+Support only vmware VRs need to run it and that too only as the last step of the setup/completion, so we don't need to run it all the time.

VMware router will be rebooted based on #2794, per current config
the VRs on reboot will go through fsck checks slowing down the deployment
process by few seconds. This will ensure that fsck checks are done
on every 3rd boot of the VR. The `4` is used because 1st boot is done
during the build of systemvmtemplate appliance.
Add upgrade path for a new 4.11.2 systemvmtemplate.
Other changes:
- Add support for XS 7.5 Fixes#2834.
- Reboot VR only if mgmt gw is not pingable on vmware.
- Enable passive ftp by enabling nf_conntrack_helper. This is change in behaviour since linux 4.7

This fixes incorrect xenstore-read binary path, this failed systemvm
to be patched/started correctly on xenserver. The other fix is to keep
the xen-domU flag that may be returned by virt-what. This effect
won't change the cmdline being consumed as the mgmt server side (java)
code sets the boot args in both xenstore and as pv args. The systemvm's
/boot is ext2 that can be booted by PyGrub on both old and recent
XenServer versions.
