SOLR-11990: Wait for all nodes to be live before running tests.
A few tests have failed on jenkins where the very first call to Solr to set the
policy fails because no live nodes were found. This commit adds a 30 second
(max) wait for nodes to be registered live in ZK before attempting to run any
test.

> It is necessary to co-locate replicas of different collection together in a
> node when cross-collection joins are performed.
> while creating a collection specify the parameter
> {{withCollection=other-collection-name}} . This ensure that Solr always
> ensure that atleast one replica of {{other-collection}} is present with this
> collection replicas
> This requires changing create collection, create shard and add replica APIs
> as well because we want a replica of collection A to be created first before
> a replica of collection B is created so that join queries etc are always
> possible.
> Some caveats to this implementation:
> # The {{other-collection}} should only have a single shard named "shard1"
> # Any replica of {{other-collection}} created by this feature will be of NRT
> type
> Removing the above caveats can be a goal of other issues.
