create shard tag ranges for name spaces using wildcards or regex matching

Nowadays to configure dynamic creation of sharded dbs/collections we need to set a tagRange for each new namespace.

By defining a wildcard namespace or regex expression to match namespaces we could dynamically allocate to a set of shards the data of these dynamically generated databases/collections:

sh.addTagRange( '$**',

,

, 'DYNAMIC' )
or
sh.addTagRange( 'prefix*.*', ... , 'DYNAMIC')
