JCLOUDS-1371: JCLOUDS-1488: list optimize prefix

Previously getBlobKeysInsideContainer returned all keys and filtered
in LocalBlobStore.  Now getBlobKeysInsideContainer filters via prefix
which can dramatically decrease the number of keys returned,
especially for the filesystem provider.  Further optimizations are
possible for delimiter.

> {{LocalBlobStore.list}} with the filesystem blobstore enumerates the entire container even when prefix and delimiter set.  The File API does not provide a way to list a subset of files except for those within a specific directory and the underlying filesystem makes no guarantees about enumeration order.  We can still optimize the case where prefix is set and delimiter is /.  Reference:
