Create cluster management tool

[Roman Simakov]

The main goal is the need to give user a tool to easy cluster installation.

And user need check the running status of each node in a cluster, dead or liveness? But I dont know where to get the liveness information, in postgres? If in postgres, We can use Collectd's PostgreSQL plugin to get.

For monitering, I also suggest Collectd to get metrics like the way of Scylladb.

If in perspective we want to drop PgSQL dependency I think better do not use it in other new tools/subsystems. For extracting metrics and monitoring we can extend our API and protocol and write our own collect'd plugin.

[yang theseus]

Ok, I agree you.

[yang theseus]

Temporarily, We don't remove PgSQL dependency, I guess the cost is more expensive.
We first keep the stability of 0.1.0, then replace it gradually.

[Roman Simakov]

Yes.

Currently implemented ansible scripts allow to init and start cluster on Ubuntu 14.04 https://bitbucket.org/phoenixdb/phdb_admin It's necessary:

1. to extend supported OSs
2. add status monitoring

[Roman Simakov]

Playbook to check status is added.

I need to check ability to manage cluster under multiple user account.
