Get beamline params from beamline files

[jacob720]

Could: This is a bit of scope creep but the way we're doing this is a bit messy. I think we can do it like we do

dodal/src/dodal/beamlines/i03.py

Line 92 in d245f0a

def daq_configuration_path() -> str:

and load it in as part of the beamline file. If that makes sense? Can you either do here or make a new issue?

Currently, we have a get_beamline_parmeters() function in dodal/common/ that can be called to retrieve beamline parameters where needed. It would be cleaner to have a per-beamline function in ixx.py, and then beamline params can be passed in to devices when initialised.

There's still a question of how to get beamline parameters in common plans.

Acceptance Criteria

• Each beamline file has a get_beamline_parameters function
• Devices that require beamline parameters recieve them when initialised.
• Common plans that require beamline parameters still work
