Feature/implement flask admin

[fumblehool]

fixes #134

[fumblehool]

@aaron-suarez this PR contains the admin routes and the access control but some UI related things like - login page UI, logout page routing is remaining.

@fumblehool Thanks so much for your contribution! I haven't pulled it down to run it just yet, but I'd like to give it a really thorough review because it changes the models.

I think that this is also going to require a migration file to update the database, right? Can we get that added and the conflicts resolved and then I'll give it a really good review? Thanks!

[fumblehool]

@aaron-suarez I've pushed the migrations + fixed the lint issues.
Please have a look.

@aaron-suarez have you tried it locally?

[aaron-junot]

So locally, I got it running in the flask shell, but I'm a bit unclear as to the interface for creating a new user and assigning roles. Would you mind commenting with an example of how to add an admin user so I can do that locally and ensure that everything works as expected?

I'm sure it's in the Flask-Login docs somewhere, feel free to just link to the relevant page in the docs if that's easier.

Thanks again for this contribution, it's looking good so far, just gotta go through the flow to make sure everything works 😄

Also, please rebase to resolve conflicts

I ran it and navigated to /login and I got this error

Let me know when you're ready for another review (because I assume you're still trying to work this out). If you need help, feel free to hit me up on slack.

@aaron-suarez I've fixed the issues -

• I missed the positional params for user_creation
• Fixed a bug in password hashing, on every run a different secret_key and `hash was used.

[aaron-junot]

In order for the tests to pass, we'll probably need a default 'SECRET_KEY' and 'SECURITY_PASSWORD_SALT'

[aaron-junot]

Other than that, it looks like it works at a first pass. I'll do some more extensive testing later, but I really appreciate the effort here!

[fumblehool]

@aaron-suarez I've added default values for secret_key and security_hash. It should work now.
Once the tests are updated, we can change/remove the default values for security reasons.

@aaron-suarez I've resolved the comment. Please review, Thanks 😄
