* Use latest go version 1.10
Pre review feedback, use the latest version of go.
Error `connection refused` was thrown when user tries to get "Alice" to
connect to "Bob" node due to port mismatch introduced in this change [1]
here.
This commit updates the port value to reflect the new change introduced in
[1].

* Update references to old port value
* Omit specifying port during lncli connect
* Fix typo
This commit revamps the existing docker configuration to allow for
developer’s to easily bring up/down a Lightning Network testbed
environment.
Configuration related bugs within the prior swarm set up have been
fixed. The launched lnd nodes are now able to properly communicate with
the primary btcd node over RPC. The auto-generated RPC script has been
scrapped in favor of hard-coding a developer-only set of RPC
credentials. With this change, it’s now possible to add/remove
additional lnd nodes in order to test more complex scenarios.
Additionally, the containers now build off of the latest Go version
(1.7).
This commit adds two Dockerfiles, along with a docker-compose file
which links the two docker files together allowing for single-command
deployment.
Using the docker-compose file, two containers are deployed. One running
btcd, and the other running lnd. Both containers share the same shared
volume mounted to the file system in order to allow land to read btcd’s
certificates for the TLS RPC connections.
Additionally, the btcd instance comes will an automatic RPC
configuration generated allowing one to use btcctl out of the box via
calls to “docker-compose exec btcctl …”.
