Refactor db_common module

[LuiggiTenorioK]

There are some high-level issues in this module that can be solved by using SQLAlchemy and applying the repository pattern.

Tasks:

• Include new search function in the join repository pattern
• Use experiment repository when needed
  • search by expid
  • get version
• Update search handlers to use the new join repository
  • v4 experiments search
  • v3 search
  • v3 running experiments
• remove dead code

Reading the code here I see nothing that I'd change, nor that looks wrong/weird 👏 👏 👏 +1!
