Separate connect/read timeouts in pylinkahead.ini

Summary

Addresses https://gitlab.indiscale.com/caosdb/customers/f-fit/management/-/issues/93 / https://gitlab.com/linkahead/linkahead-pylib/-/issues/127
It is now possible to set separate connect/read timeouts or timeout None in pylinkahead.ini.

Corresponding Test-MR: caosdb-pyinttest!86 (merged)

Focus

• Is the CustomValidator an acceptable solution to the validation of tuples as array?
• Are there any cornercases where this breaks a request that I missed?
