[pgpool-committers: 5019] pgpool: Encrypted password support for Pgpool-II internal backend conne

[Muhammad Usama]

Encrypted password support for Pgpool-II internal backend connections.

The commit allows to specify the AES encrypted password in the pgpool.conf file
for healh_check_user, sr_check_user, wd_lifecheck_user and recovery_user users,
Additionally if the password field for any of these users is left blank in
pgpool conf then Pgpool-II will first try to get the password for that user
from pool_passwd file before using the empty password for the connection.
So now pgpool.conf can be made password free and single pool_passwd file can be
used to store all passwords for internal and external user connection
