cache: support more segtypes for caching

Browse Source 
Enable support to cache thin/error/zero virtual targets.

Use can now select whether he want to cache whole thin-pool,
or an individual thin volume out of whole thin-pool.
Support using zero and error LVs as data volume for
cachepool is possibly useful for benchmarking, not much
can be expected from such setup.
