Add validation that samples within a case have the same analysis type

[diitaz93]

As a systems developer,
I want the AnalyisAPI not doing database validations. Specifically, I would like the validation that all samples within a case should have the same AnalysisType done in this method to be implemented in the ordering,
So that we don't need to do database validations in the AnalysisAPI and the separation of concerns is respected.

Work impact

Answer the following questions:

• Is there currently a workaround for this issue? If so, what is it?
  • No
• How much time would be saved by implementing this feature on a weekly basis?
  • Nothing
• How many users are affected by this issue?
  • System developers and Bioinfo developers interacting with the AnalysisAPI
• Are customers affected by this issue?
  • No

Acceptance Criteria

• There is a validation rule in the ordering service that verifies that all samples within a case have the same analysis type (i.e. TGS, WES, WGS or WTS) for all pipelines except MIP-DNA
• The validation in the AnalysisAPI is removed as is no longer needed
  ...

Notes

• This is blocking the subissue [Pipeline integration] Create correctly the params file for raredisease #4239 and therefore, the merging of DEV - Start pipelines #4227 (as the validation in the configurator is not going to be included)
• Already discussed with @jemten

Is this not a very weird check to have in the first place

So basically return "wts" if WTS application. If not, return "wgs" if WGS application, and all other applications get the "wes" analysis type? So all applications but WTS and WGS get WES as analysis type?
