Pull Request

Description

• Added the ability to upload a file with videos and save it into the database (Controller LibraryImportController)
• Added compose.yml to spin up PostgreSQL
• Added method getVideoData to VideoController and other methods in consequent services to retrieve video data from YouTube API
• As a part of enhancing the codebase, I added the method getToken to the TokenService to retrieve the token from Spring's authorized client. This should allow us not to pass @RegisteredOAuth2AuthorizedClient OAuth2AuthorizedClient authClient as a parameter to controllers

To make things work in IntelliJ IDEA you'd need to set the environment variables in the run configuration:

Amaaaazing job, really
I've left a few small comments for clairfication purposes mosly)

just out of curiosity - why do we need a volume here?

[leingenm]

So the data is persistent even if we stop and start a container with PostgreSQL. But I see a point in not making it persistent
