Add beast init for Issue 417

Primary Changes:

• Creates .beast directories
• Creates beast_authorized_keys file in accordance to the example config. Does not create a secret.key since no usages were found
• Creates a global config file from example config if not found
• Validates the docker daemon is running
• Installs air for live reloads
• Prompts the user and creates a beast postgres database
• Prompts the user and creates an admin user

Secondary Change:

• Remove unused init from main.go
• beast run checks for existence of .beast folders before running

[kunrex]

Implemented Suggestions

• beast config is used to interactively set up the global beast config
• beast init now checks the existence of the beast postgres user and database as well as calls beast config internally

Also,@kunrex, I would like to have a demo run for this before approving changes.

[v1bh475u]

May be we can have the correctly parsed incomplete time with some fix instead of defaulting to now. Thoughts?

[kunrex]

so we just default it to something if it fails? like if it fails on hours then just default it to 00 minutes, UTC or smthg like that?

[v1bh475u]

Yeah. Something of that sorts. However, I am not too convinced of the idea and would like to know your opinion on the same.

[kunrex]

yeah i think its better than now, also the prompt only really fails if the user ctrl+c', with that in mind what can we default it to?
