Development: Update Dockerfile and create possibility to run local cluster
...
To help in developing features, the Dockerfile and its entrypoint have been extended.
The README.md explains stuff in detail, in short:
- you can now run a Patroni cluster with a single command

Updated Dockerfile
...
Due to the renaming of Governor to Patroni some old references needed to be updated.
Also some python packages need to be added.
Added entrypoint.sh as a script, to ensure Patroni will have PID = 1 when the container is run.

Adoprt WAL-E related code for a stand-alone script.

- make sure all parameters are taken from the env variables.
- make sure WAL-E code is not involved if the image is not configured for it
- pick up pg_basebackup as an alternative if WAL-E fails.
The WAL-E support will be switched on in subsequent commits.

Merge pull request #7 from zalando/feature/callbacks
...
Implement callback actions for patroni in order to call external script on different events in the server lifecycle, supported are on start, stop, restart, reload and role change (which covers both promote and demote). A callback should receive 3 arguments: action, role and cluster name (in this order), and can do things like tagging the EC2 instances associated with PostgreSQL, or notifying the DBA when the master had been demoted.
A sample callback that assigns tags to AWS instances is provided.

Be more robust on callbacks when cluster is down.
...
For 'on_stop' or 'on_restart' callbacks we cannot
call is_leader, because the cluster would be stopped.
Instead, call is_leader before running a callback.
In addition, make the call_nowait more robust by handling
the exceptions related to the DB cluster unavailability.
