FailSafe - a slack bot that invokes other slack bots

Zeta is complicated; failsafe is not.

Failsafes job is to ensure that zeta is running.

To accomplish this goal we:

1. Copy a script over to our "working directory"
2. Execute a script on the machine where zeta can run.

• Script checks to see if the process+db is running
• If it's running return early
• If not running: start a new process in tmux.

Usage

# runtime needs this:
$ export SLACK_API_TOKEN=xxxx

# compiler needs this:
$ export SSH_USER=xxxx
$ export SSH_HOST=xxxx
$ export SSH_PASS=xxxx
$ cargo run
