Implement user login, complete with self server password administration to establish API key for REST endpoint authentication.

Motivation and context
The REST endpoints are needed to share PE Reports data to 3rd party as well as inter agency partners. The api key and associated login management are needed to safely control endpoint usage.

Implementation notes
The user that has a need to consume PE Reports data, would register with the REST system. The user would create a username and password that would create an API key that would then be used to make API calls and return data to the user programmatically. The REST endpoint will work in conjunction with our current Flask application #115.

-Remaining tasks

• Create api token.(This task is similar to creating the reset token)
• API can be accessed alongside of pe-reports generator
• Create dependent functions to pull API user functions.
• Create REST api endpoint and apply authorization technique utilizing api token
• Create a user page to display the user api key
• Check access token for expiration
• Create endpoint to self admin new api keys

Acceptance criteria
How do we know when this work is done?

• All testing checks will pass.
• Code in P&E repo will be treated as authoritative
• Team source code collaboration will be done through P&E repo rather than via Teams
• User will be able to create a new account.
• Self administer password resets.
• Receive API key to interact with PE Reports data.
