This patch add trace log for the db access. Currently support
5 log levels:
- 0: disable the trace log for db.
- 1: trace the calls of database subroutines.
- 2: trace the event to build the cache for the table
- 3: trace the event with cache hit
- 4: trace the SQL statement

* xCAT-client: allow pgsqlsetup(1) to accept additional pg_hba.conf entries
Currently pgsqlsetup(1) only sets up the MN ip address for access via
pg_hba.conf. This change adds a -a flag to allow the user to specify
additional addresses for use in that file.
This is useful for users who already know what IP addresses will be
used by their service nodes, so they can pass them directly to the
pgsqlsetup program, without needing to edit pg_hba.conf (and avoiding
needing to restart postgresql and xcat after the edit).
* xCAT-client: fix formatting in pgsqlsetup(1)
* pgsqlsetup.1.pod: clarify default setup
* pgsqlsetup.1.pod: update usage section to reflect access flag
* pgsqlsetup.1: refresh documentation
* xCAT-client/bin/pgsqlsetup: add -a/--access to usage statement
2, handle 'disjoint' in preprocess method, to make sure that no request will be sent to SN which does not manage the nodes.
3, refine 'stat' to make sure it could query unmanaged nodes on-demand.
This patch redesign the original getadapter plugins. Currently,
getadapter do not work as a common command but only a chain command
works during discovery.
for the supported options based on the possible values that are
currently allowed to be returned. As more data is added, the code
should be able to handle the printing of the data automatically
