Updated Dockerfile to remove USER line, as that prevents proper file
mapping writing.
Updated compose file to map to /app/data where the database is supposed
to be.
Split Json data models coming from REST Api, from the Database models
storing them in a SQLite database.
Work to re-engineer endpoints to use Database objects, and copy/update
data from the json objects.
More work is needed.
Updated all endpoints to use Update() method of the model, instead of
trying to use the data from the REST object directly to update the
database. WHen doing so, tracking gets busted in EFCore, so instead,
will go through and update all properties of a model from the database
object, with the data from the REST object.
Updated Program to have SQLite Configuration done through Connection
Strings.
Added auto migration for the database, if we get an exception, we create
the database instead (As it doesn't exist.)
Updated Migrations to handle change of Int to Long (SQLite still uses
integer field, but better safe if using something other then SQLite)
Changed Primary Key for Video from VideoId to PlaylistItemId.
Removed videoId as Key, and use playlistItemId as Key, as this will be
unique to each playlist, and will not conflict with videos being on more
then one playlist.
