Added replicaset name to bigchaindb config (#1063)

Browse Source 
* Added replicaset name to bigchaindb config

* changed travis replSet to match bigchaindb default

* Updated initialize_replica_set

It now initializes the replica set with the name provided by the
bigchaindb config file.


* initialize_replica_set is now called when creating a mongodb connection.

This way we are sure that a replica set exists when we return a
connection.

* Moved the initialize replica set logic to the connection.

* update the config documentation

**Note**: As of now, only RethinkDB ("rethinkdb") is supported as a value for `database.backend`. In
the future, other options (e.g. MongoDB) will be available.
**Note**: We are currently adding support for MongoDB. The `replicaset` and
`BIGCHAINDB_DATABASE_REPLICASET` option is only used if the `backend` or
`BIGCHAINDB_DATABASE_BACKEND` is set to `"mongodb"`.
