VIRA-293: allow access token auth

[jacobstr]

• Tested access_token and access_token_cmd.
• Have not tested for regressions with username and password. Fixes #76

Sorry I have been "away" for a bit. I am going to take a look at all the new posted issues then a real look into this one.

I am currently getting the error:

No `vira_servers.json/yaml` file found or, check the config! See `README.md` for more information.

KeyError: 'basic_auth'

I am sure there is a quick fix for it but I am going to look into why it turned backwards on us to try and catch it with the proper try/catch

[n0v1c3]

I even knew I didn't look close enough at it. The core of the problem for the existing users will be the == on line 198 this was supposed to be an = for the group you were not as worried about ;-).

Keeping it working would be the nicest I can do the merge and the fix or you can do the fix if you would like. If it still works for both of us I will release it to master and do a backwards merge with dev and then back into the master branch.

Heh thanks @n0v1c3 - I'm fine if you patch it up since you were able to repro it and will be on deck to validate the fix. I ran through a few scenarios by hand but clearly missed this.

[n0v1c3]

I assumed it was as simple as that. I wall get it done today and VIRA-293 can just be done with.

@jacobstr Please keep finding more to make it even safer for our users.

[n0v1c3]

@jacobstr I currently have an open branch due to development VIRA-293 should exist until the full merge is complete.

I implemented this feature a few months ago. Can you confirm if it works for you, please?
