DG: Farsync configuration in clusterware

To register an existing farsync instance in the clusterware:

srvctl add database -db <db> -oraclehome /u01/app/oracle/product/ -startoption mount -spfile +DATA/<db>/spfile<db>s.ora -pwfile +DATA/<db>/orapw<db>

To copy the password file from the filesystem, use pwcopy:

ASMCMD> pwcopy /tmp/<pwfile> to +DATA/<db>

As far as the spfile is concerned, the method so far is to use the standard method to copy from dummy pfile.
