Paul Angus 033199972e systemvm: improve SystemVM startup and memory usage (#3126) ...

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
