feat(authentication): POC Login System

[jackcmeyer]

Changes proposed in this pull request:

• refactors HospitalRun to use one local db (adds relational-pouch to help with this)
• adds pouchdb-authentication for authentication helper
• adds example Docker setup to connect to remote db (and a docker compose file to launch this db)

My main goals in this PR were:

• to create some resemblance of login/logout against PouchDB/CouchDB so we can iterate on it
• to create some login/logout so we can start work on user based things (i.e. user preferences)
• refactor the db to use one db so we can start working on connecting the application to the server

What this pull request doesn't do

• gracefully handle logout. Ideally we clear the localdb, or make it unaccessible some how.
• add tests for the Login screen (I anticipate this is going to change, so I felt that adding tests for this POC did not have much value)
• gracefully handle a session expiring (right now, if a user signed in via hospital run, but then ended their session in fauxton, HospitalRun would not gracefully handle that). Ideally, on the next user action, it would log them out.
• in any shape or form create a production ready login system
• connect permissions to couchdb

For things that this PR does not address, we should open new issues when this PR is merged.

What is left to finish this PR?

• configure staging.hospitalrun.io to connect to some remote couchdb instance
• ensure that the documentation is clear
• fix translations

Newly added dependencies with Bundlephobia links:

• relational-pouch
• pouchdb-authentication
