Machine resources for livepatch on-prem

The resource requirements for machines running livepatch on-prem components (postgresql, haproxy, livepatch) depend on the amount of machines being serviced by the deployment.

Minimal requirements are:

Service Memory CPUs Disk
postgresql 4GB 1 50GB
haproxy 2GB 1 50GB
livepatch 2GB 1 50GB

If postgresql is going to be used as the patchstore, we recommend increasing disk allocated to posgresql to 100GB.
