2. Move tde keys and keyring when chaging tablespace …

   When a relation moved to a new location it causes the change of relfilenode id
   for it. Hence we must re-encrypt and store its internal key with the new id.
   Also, we have to store the changed internal key in the new physical location,
   and copy there principal key info and keyring data.

3. Store rel key type along with internal key …

   This is needed for ALTER  TABLESPACE as pg_tdeam_relation_copy_data
   gets only the old rlocator and needs to know how to properly save the
   key in the new rlocator.
   
   Also during ALTER ... TABLESPACE, tde_mdcreate gets called and
   tde_smgr_get_key is trying to get the internal key. But there is no key
   moved to the new table space since it is called during
   RelationCreateStorage() and pg_tde.map file might not exist. And it's ok in
   this case but it results in an error. This commit introduces an option not
   to have a pg_tde.map (treated as no key).
