Subject: [PATCH 1/3] CTDB: support Samba 4.9+
With Samba 4.9+, all ctdbd parameters have moved to config files.
Generate a new /etc/ctdb/ctdb.conf file during ctdb startup, based on RA
configuration.
Event scripts in Samba 4.9+ are also no longer enabled/disabled based on
file mode. Use the "ctdb event script enable/disable" helpers, which now
work without a running ctdbd.
Fixes: https://github.com/ClusterLabs/resource-agents/issues/1196

Subject: [PATCH 3/3] CTDB: drop sysconfig presence check during validate
There are two reasons to avoid this check:
- for ctdb versions prior to 4.9.0, the sysconfig file is generated by
the resource agent start hook *after* ctdb_validate() is called.
- post 4.9.0 versions don't use the sysconfig file.
