`ProxmoxCluster.spec.SchedulerHints.MemoryAdjustment=300` allows to (theoretically) allocate 300% of a host's memory for VMs (use with caution - enabling memory ballooning highly recommended)
`ProxmoxCluster.spec.SchedulerHints.MemoryAdjustment=95` allows to limit memory allocation to 95% of a host's memory
`ProxmoxCluster.spec.SchedulerHints.MemoryAdjustment=0` entirely disables scheduling memory constraints
Previously, it was only checked for VMs, without taking their Template status into consideration. (A Template VM can't be started, without explicitly removing the flag.). Existing LXCs on a host weren't taken into consideration either.
Now, we'll no longer include VM Template in our calculations. But in exchange we include LXCs now.
Fixes#36.
