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

vr: memory and swap optimizations (#2892)
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.

systemvm: export $TYPE before patching ssvm/cpvm (#2855)
This fixes a regression introduced in #2799, by exporting $TYPE
before the `patch` is called to patch/extract archives for ssvm/cpvm.

systemvmtemplate: new 4.11.2 template and fixes (#2799)
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
