Chandan Kumar (raukadah) 9dea55bd64 Drop code from Host maintenance strategy migrating instance to disabled hosts ...

Currently host maintenance strategy also migrate instances from maintenance
node to watcher_disabled compute nodes.

watcher_disabled compute nodes might be disabled for some other purpose
by different strategy. If host maintenace use those compute nodes for
migration, It might affect customer workloads.

Host maintenance strategy should never touch disabled hosts unless the user
specify a disable host as backup node.

This cr drops the logic for using disabled compute node for maintenance.
Host maintaince is already using nova schedular for migrating the
instance, will use the same. If there is no available node, strategy
will fail.

Closes-Bug: #2109945
