New microservices image with working RunServices

[TiagoTAlves]

This Pull Request creates a RunNumber, RunRegistryMeta and RunRegistryConfigs table which allows for the storage of run services data related to nanorc in daq-kube.
These changes will be used to create a unified microservices image which will find the run services postgresql pod which has a database already deployed and add the tables to the already created database. These tables are created using flask_sqlalchemy.
All mentions of Oracle have been replaced with PostgresSQL.

The structure of these is as follows (for both both runnumber-rest and runregistry-rest):

• A rest.py - This calls upon the other python files and creates the applications
• A datbase.py - This creates the tables as python classes using flask_sqlalchemy
• A authentication.py - This creates a username and password to access the API's
• An api.py - This creates the api queries for accessing and inserting data into the database using sqlalchemy directly
• An entrypoint.sh - This creates and entrypoint for the respective runservice in the image
• A deployment.yaml - This is a copy of the deployment.yaml file in daq-kube

This PR also requires the https://github.com/DUNE-DAQ/daq-kube/pull/35 to be approved too.

TODO: Need to create new microservices dependencies image as well as microservices image

Why did you close this out?

[TiagoTAlves]

I closed it because people were getting confused between both pull requests, once the other was merged I'd reopen the request. If you think this is the wrong approach we could open it again

This is the one with the actual python changes. If you're talking about the daq-kube pr, I'd close that one and re-open this instead.
