This change adds cleanup mechanism to archive by following steps:
1) add archive_cleanup.sh under /tmp directory
2) through the start.sh this script will be triggered
3) It runs every hour, checking utilization of archive dir
4) If it is above threshold it deletes half of old files

This reverts commit 982e3754a5.
"Add default reject rule end in Postgres pg_hba.conf to ensure all
connections must be explicitly allowed."
The original commit introduced a breaking change when installing with
the chart defaults - before, all remote connections with md5 auth were
allowed, and after the change, only explicit users are allowed.
This is fully overridable, but the original defaults are more
conservative.

* add preStop hook to trigger Fast Shutdown
* disable readiness probe by default
When Kubernetes terminates a pod, the container runtime typically sends
a SIGTERM signal to pid 1 in each container [0]. PostgreSQL interprets
SIGTERM as a request to do a "Smart Shutdown" [1]. This can take minutes
(often exhausting the termination grace period), and during this time,
new connections are not being serviced.
Now that postgresql has a single replica, this behavior is undesirable.
If we kill the pod (e.g. in an upgrade), we probably want it to come
back as soon as possible.
This change adds a preStop hook that sends a SIGINT to postgresql in
order to trigger a "Fast Shutdown". In addition, the readiness probe is
disabled by default, since it adds no value in a single-replica
scenario.

Uses the standard helm-toolkit macros for liveness and readiness probes,
allowing them to be enabled or disabled, and params to be overridden.
The existing hard-coded settings are preserved as the chart defaults.

It appears having `args:` without `command:` causes some combinations
of kubernetes & container runtimes to not work as expected.

To safeguard postgres from clogging up wal files
in pg_xlog directory, This change does the following:
1) adding postgres archiving to move the WAL file to different directory
2) Makes sure that archive is in different Persistent volume.

This commit rewrites lint job to make template linting available.
Currently yamllint is run in warning mode against all templates
rendered with default values. Duplicates detected and issues will be
addressed in subsequent commits.
Also all y*ml files are added for linting and corresponding code changes
are made. For non-templates warning rules are disabled to improve
readability. Chart and requirements yamls are also modified in the name
of consistency.

The current copyright refers to a non-existent group
"openstack helm authors" with often out-of-date references that
are confusing when adding a new file to the repo.
This change removes all references to this copyright by the
non-existent group and any blank lines underneath.
