Proof of Concept Deploy Key

[chadlagore]

As a result of calling inertia init <vps_ip> <github_repo> (locally), at least the following steps should take place:

0. Inertia gets installed on the VPS.
1. Create a key pair locally.
2. Show the public key to the user (they copy-pasta to GitHub).
3. Pipe the pem file to the VPS ssh <vps_ip> 'bash -c' < inerta set-key <key> <repo>.
4. Show the webhook url to the user locally (they copy-pasta to GitHub.

OR, if we opt to call inertia init on the VPS kill step 3 and replace step 0 with ssh <vps_ip>:

Example:

$> inertia init <vps_ip> <github_repo>

😏 Your new inertia public deploy key (add it here https://github.com/<user>/<repo>/settings/keys/new):
ssh-rsa AAAAB3NzaC1yc2EAA...

Enter VPS SSH password: *****************

🎉 Your new inertia GitHub webhook URL (add it here https://github.com/<user>/<repo>/settings/hooks/new):
https://<vps_ip>:8888

$>

Note: (2) can actually be done with:

curl -kX POST -u <user> https://api.github.com/repos/<user>/<repository>/keys \
    -d '{
    "key": "<public-key>", 
    "read_only": true, 
    "title": "inertia"
}'

# Prompts for GitHub password :(

but then the user has to login to github via inertia, which seems bad - but might be OK? This can be done with OAuth too, but is OAuth in scope for MVP?
