Refactor sqlite3 to SQLAlchemy

[LuiggiTenorioK]

The purpose of this PR is to remove the usage of the sqlite3 and use SQLAlchemy instead. We will exclude the refactor of the history module to another branch.

• autosubmit_api/database/db_structure.py
• autosubmit_api/experiment/common_db_requests.py
• Remove some dead code

Read the code but didn't find anything that looked odd or out of its place. Nice simplification and it's impressive how much code was deleted here (minus 463 lines of code, adding only 71). I assume some of those functions removed were never used?

Yes, many methods of the history db manager were never used. I'll continue that history module refactor on another since this one seems pretty clean.
