framework/db: use HikariCP as default and improvements (#9518)
Per docs, if the mysql connector is JDBC2 compliant then it should use
the Connection.isValid API to test a connection.
(https://docs.oracle.com/javase/8/docs/api/java/sql/Connection.html#isValid-int-)

This would significantly reduce query lags and API throughput, as for
every SQL query one or two SELECT 1 are performed everytime a Connection
is given to application logic.

This should only be accepted when the driver is JDBC4 complaint.

As per the docs, the connector-j can use /* ping */ before calling
SELECT 1 to have light weight application pings to the server:
https://dev.mysql.com/doc/connector-j/en/connector-j-usagenotes-j2ee-concepts-connection-pooling.html

Replaces dbcp2 connection pool library with more performant HikariCP.
With this unit tests are failing but build is passing.

Add influxdb to statscollector (#3078)
* Add Support for InfluxDB on StatsCollector

* Code refactored to fit Inner Class architecture.

Due to the inner class structure, test case for some methods will not be
implemented. On the future it will be necessary to refactor the whole
StatsCOllector architecture and extract inner classes.

Each Inner Class that is a "stats collector" and sends data to Influx
will extend AbstractStatsCollector to send metrics to the correct
measure ("table"). For instance, HostCollector sends data to host_stats,
VmStatsCollector sends data to vm_stats.

Add ping test for ensure that the target InfluxDB host is reachable

* Address PR reviews

* Enhance and tests implemented addressing reviewers.

* Set variables to private

CLOUDSTACK-10290: allow config drives on primary storage for KVM (#2651)
This introduces a new global setting `vm.configdrive.primarypool.enabled` to toggle creation/hosting of config drive iso files on primary storage, the default will be false causing them to be hosted on secondary storage. The current support is limited from hypervisor resource side and in current implementation limited to `KVM` only. The next big change is that config drive is created at a temporary location by management server and shipped to either KVM or SSVM agent via cmd-answer pattern, the data of which is not logged in logs. This saves us from adding genisoimage dependency on cloudstack-agent pkg.

The APIs to reset ssh public key, password and user-data (via update VM API) requires that VM should be shutdown. Therefore, in the refactoring I removed the case of updation of existing ISO. If there are objections I'll re-put the strategy to detach+attach new config iso as a way of updation. In the refactored implementation, the folder name is changed to lower-cased configdrive. And during VM start, migration or shutdown/removal if primary storage is enable for use, the KVM agent will handle cleanup tasks otherwise SSVM agent will handle them.

fbf07fa565 server: Remote empty VPN test class (#2587)
I found this empty test while working on other PRs. Empty/ignored tests do not help us. I am removing it. In the future, if we manage to improve these classes, we can work on unit test cases for them.

CLOUDSTACK-10132: Extend support for management servers LB for agents (#2469)
The new CA framework introduced basic support for comma-separated
list of management servers for agent, which makes an external LB
unnecessary.

This extends that feature to implement LB sorting algorithms that
sorts the management server list before they are sent to the agents.
This adds a central intelligence in the management server and adds
additional enhancements to Agent class to be algorithm aware and
have a background mechanism to check/fallback to preferred management
server (assumed as the first in the list). This is support for any
indirect agent such as the KVM, CPVM and SSVM agent, and would
provide support for management server host migration during upgrade
(when instead of in-place, new hosts are used to setup new mgmt server).

This FR introduces two new global settings:

- `indirect.agent.lb.algorithm`: The algorithm for the indirect agent LB.
- `indirect.agent.lb.check.interval`: The preferred host check interval
  for the agent's background task that checks and switches to agent's
  preferred host.

The indirect.agent.lb.algorithm supports following algorithm options:

- static: use the list as provided.
- roundrobin: evenly spreads hosts across management servers based on
  host's id.
- shuffle: (pseudo) randomly sorts the list (not recommended for production).

Any changes to the global settings - `indirect.agent.lb.algorithm` and
`host` does not require restarting of the mangement server(s) and the
agents. A message bus based system dynamically reacts to change in these
global settings and propagates them to all connected agents.

Comma-separated management server list is propagated to agents on
following cases:
- Addition of a host (including ssvm, cpvm systevms).
- Connection or reconnection by the agents to a management server.
- After admin changes the 'host' and/or the
  'indirect.agent.lb.algorithm' global settings.

On the agent side, the 'host' setting is saved in its properties file as:
`host=<comma separated addresses>@<algorithm name>`.

First the agent connects to the management server and sends its current
management server list, which is compared by the management server and
in case of failure a new/update list is sent for the agent to persist.

From the agent's perspective, the first address in the propagated list
will be considered the preferred host. A new background task can be
activated by configuring the `indirect.agent.lb.check.interval` which is
a cluster level global setting from CloudStack and admins can also
override this by configuring the 'host.lb.check.interval' in the
`agent.properties` file.

Every time agent gets a ms-host list and the algorithm, the host specific
background check interval is also sent and it dynamically reconfigures
the background task without need to restart agents.

Note: The 'static' and 'roundrobin' algorithms, strictly checks for the
order as expected by them, however, the 'shuffle' algorithm just checks
for content and not the order of the comma separate ms host addresses.
