A collection may be co-located with another collection during collection creation time by specifying a
'withCollection' parameter. It can also be co-located afterwards by using the modify collection API.
The co-location guarantee is enforced regardless of future cluster operations whether they are invoked
manually via the Collection API or automatically by the Autoscaling framework.

SOLR-11990: Extract ConditionType to an interface VarType along with a WithCollectionVarType implementation
commit 1de2a4f52a59afca28de75bfa5156a3d6567a4f5
Author: Shalin Shekhar Mangar <shalin@apache.org>
Date: Tue Jul 24 12:53:26 2018 +0530
SOLR-11990: Pass strict-ness parameter to the ConditionType so that WITH_COLLECTION can choose not to project add replica in strict mode.
This ensures that add replica or move replica suggesters always choose nodes that already have withCollection replicas first unless there are violations in doing so. Only if the first pass fails to find a suitable replica, do we go to the other nodes in the cluster. This also removes the need for the majority of changes in AddReplicaSuggester and so they've been reverted.
