Implementation of ipfs as private network

[robinportigliatti]

Hello jeffbr13,

Just wanted to use your role but the implementation of ipfs as a private network seems to be missing.

The idea is to remove all informations in Bootstrap like this and add one line:

[...]
  "Bootstrap": [
    "/ip4/{{ ipfs_bootstrap_ip_address }}/tcp/4001/p2p/{{ ipfs_bootstrap_peer_id }}"
  ],
[...]

And generate a swarm key inside /home/ipfs/.ipfs/swarm.key.

I finished the work partially, I can help by making a pull request in the near future.

Let me know
