[envsec] Don't require git repo

[mikeland73]

Summary

TSIA

In a follow up, I'll improve project name when not in github repo.

How was it tested?

envsec init (not in repo)

LGTM ... although once this is in, I have two questions:

1. How will GetOrCreate work? I thought the name of the repo is a key parameter to it
2. Will we add the "link" functionality? Or rather: in a different computer how do I associate a directory with an existing project that has no git repo?

@loreto I was thinking of a prompt that allows user to pick an existing project or create a new one. Something like

envsec init
* project 1
* project 2
* project 3
* Create new project

Something along those lines.

So we may not end up needing GetOrCreate TBD
