Allow a VM to specify its migration type as a default choice. The valid
options are "default" (i.e. behave as now), "live" which forces a live
migration only, and "shutdown" which forces a shutdown migration only.
The new option is treated as a VM meta option and is set to default if
not found.
Adds a separate field to the node memory, "provisioned", which totals
the amount of memory provisioned to all VMs on the node, regardless of
state, and in contrast to "allocated" which only counts running VMs.
Allows for the detection of potential overprovisioned states when
factoring in non-running VMs.
Includes the supporting code to get this data, since the original
implementation of VM memory selection was dependent on the VM being
running and getting this from libvirt. Now, if the VM is not active, it
gets this from the domain XML instead.
Since these will almost always connect to an IP rather than a "real"
hostname, don't verify the SSL cert (if applicable). Also allow the
overriding of SSL verification via an environment variable.
As a consequence, to reduce spam, SSL warnings are disabled for urllib3.
Instead, we warn in the "Using cluster" output whenever verification is
disabled.
Don't try to chmod every time, instead only chmod when first creating
the file. Also allow loading the default permission from an envvar
rather than hardcoding it.
Provide textual explanations for the degraded status, including
specific node/VM/OSD issues as well as detailed Ceph health. "Single
pane of glass" mentality.
Makes this output a little more realistic and allows proper monitoring
of the Ceph cluster status (separate from the PVC status which is
tracking only OSD up/in state).
Allow the specifying of arbitrary provisioner script install() args on
the provisioner create CLI, either overriding or adding additional
per-VM arguments to those found in the profile. Reference example is
setting a "vm_fqdn" on a per-run basis.
