* This method lets you construct a complex ClusterState object by using simple strings of letters.
*
* c = collection, s = slice, r = replica, \d = node number (r2 means the replica is on node 2),
* state = [A,R,D,F], * = replica to replace, binds to the left.
*
* For example:
* csrr2rD*sr2csr
*
* Creates:
*
* 'csrr2rD*'
* A collection, a shard, a replica on node 1 (the default) that is active (the default), a replica on node 2, and a replica on node 1
* that has a state of down and is the replica we will be looking to put somewhere else (the *).
*
* 'sr2'
* Then, another shard that has a replica on node 2.
*
* 'csr'
* Then, another collection that has a shard with a single active replica on node 1.
*
* Result:
* {
* "collection2":{
* "maxShardsPerNode":"1",
* "replicationFactor":"1",
* "shards":{"slice1":{
