Migrate Bigchaindb cli for Tendermint

Problem Description

With Tendermint integration some of the cli sub-commands have been rendered obsolete. It would be only appropriate to remove those sub-commands.

Use cases

• Avoid confusing the user by not displaying irrelevant sub-commands.

Proposed Change

Following sub-commands should be updated/removed:

• planetmint --help: list the relevant sub-commands for localmongodb backend. mongodb and rethinkdb will be deprecated. In case the backend is not configured then the default backend localmongodb should be assumed.

Following sub-commands should be deprecated for localmongodb backend.

• planetmint export-my-pubkey
  • A Planetmint node still has a public key but that is not Planetmint concern. It is handled by Tendermint.
• planetmint set-shards
  • This was only required for rethinkdb.
• planetmint set-replicas
  • This was only required for rethinkdb.
• planetmint add-replicas
  • This was only required for mongodb backend to add nodes to the MongoDB Replica Set, which is not required anymore, because we are using standalone MongoDB instances i.e. localmongodb.
• planetmint remove-replicas
  • This was only required for backend to remove nodes from the MongoDB Replica Set, which is not required anymore.

Usage example

planetmint

$ planetmint --help
usage: planetmint [-h] [-c CONFIG] [-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}]
                  [-y] [-v]
                  {configure,show-config,init,drop,start}
                  ...

Control your Planetmint node.

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        Specify the location of the configuration file (use
                        "-" for stdout)
  -l {DEBUG,INFO,WARNING,ERROR,CRITICAL}, --log-level {DEBUG,INFO,WARNING,ERROR,CRITICAL}
                        Log level
  -y, --yes, --yes-please
                        Assume "yes" as answer to all prompts and run non-
                        interactively
  -v, --version         show program's version number and exit

Commands:
  {configure,show-config,export-my-pubkey,init,drop,start,set-shards,set-replicas,add-replicas,remove-replicas}

Testing impact

Following test cases should be added

• Set a backend other than localmongodb and see of it results in a valid unsupported result.
• Set localmongodb as backend and execute planetmint --help and validate that only the above mentioned sub-commands are displayed.
