In this commit we fix a newly introduce bug wherein we would close the
transaction subscription twice on shutdown. This would lead to a
shutdown, but an unclean one as it would panic due to closing a channel
twice.
We fix this my removing a defer statement such that, we’ll only cancel
the subscription once.
This commit adds the +build !rpctest build flag to the test files in
the main package other than the RPC tests. With this, if the protest
build flag is set, then ONLY those tests will be run.
This commit adds a new file to the repo: pilot.go. This files contains
the items necessary to configure, and initialize an instance of
autopilot.Agent with the passed configuration struct.
