SOLR-13325: Add a collection selector to ComputePlanAction (#1512)
ComputePlanAction now supports a collection selector of the form `collections:
{policy: my_policy}` which can be used to select multiple collections that
match collection property/value pairs. This is useful to maintain a whitelist
of collections for which actions should be taken without needing to hard-code
the collection names. The collection hints are pushed down to the policy engine
so operations for non-matching collections are not computed at all. The
AutoAddReplicasPlanAction now becomes a thin shim over ComputePlanAction and
simply adds a collection selector for the collection property
autoAddReplicas=true.

> Similar to SOLR-13273, it'd be nice to have a collection selector that
> applies to compute plan action. An example use-case would be to selectively
> add replicas on new nodes for certain collections only.
> Here is a selector that returns collections that match the given collection
> property/value pair:
> {code}
> "collection": {"property_name": "property_value"}
> {code}
> Here's another selector that returns collections that have the given policy
> applied
> {code}
> "collection": {"#policy": "policy_name"}
> {code}
