LinkAhead rename lvl 0

Summary

LinkAhead Rename; First step with no action required for users.

Focus

Due to the renaming the 'Changes' tab in this MRis basically useless. Please have a look at the changes in !113 (closed) instead. The branch of this MR is created from the other one by renaming the module and by creating a thin wrapper with the old name.

The main changes are:

• renaming in docs
• renamed CaosDBException; deprecated old version exists; catching CaosDBException also catches the new one
• renamed CaosDBConnectionError; deprecated old version exists; catching CaosDBException also catches the new one
• old ini paths are deprecated, but still work. The new inis however take precedence over old ones
• caosdb_admin->linkahead_admin ; both can be used now.
• changed imports to relative or to linkahead

Test Environment

• check that the exception test properly and sufficiently tests that the exceptions are properly deprecated
• this pipeline
• test manually that you can use both admins scipts and that they are both in the path. The old one creates a warning.
• manually test the deprecation of the old ini file names and make sure that the content is still considered
• integration test [dev] against this branch: caosdb-pyinttest!66 (and check that we did test against the correct pylib version)
• check that there are no unexpected changes necessary in caosdb-pyinttest!66

Merge Procedure

• review changes in !113 (closed)
• make sure above named tests pass
• merge !112 (merged)
• delete !113 (closed)
