[webservice] Select partition based on beamtime dates

Description

Beamtimes can be active for a longer period of time, even though there is no user experiment ongoing, for reasons such as compensation time.
This leads to a problem where the jobs for such proposals are ran with high priority, although they're on ongoing. MyMDC provides information regarding the beamtime, on top of the proposal status, with the begin and end dates.

These dates, as well as the proposal status, are now used to select the correct slurm partition.

How Has This Been Tested?

The changes were tested with the test installation with the following settings:

Proposal	Run	Action	Proposal Status	Beamtime	Expected Partition
900113	9999	correct	FR	2019-12-12T13:54:29.000+01:00 - 2019-12-17T13:54:29.000+01:00	exfel
900113	9999	correct	A	2019-12-17T13:54:29.000+01:00 - 2019-12-17T13:54:29.000+01:00	exfel
3014	267	dark	FR	2022-08-31T15:29:37.902435 - 2022-09-02T15:30:06.322790 (ongoing as of this MR)	upex-high
3014	267	correct	A	2022-08-31T15:29:37.902435 - 2022-09-02T15:30:06.322790 (ongoing as of this MR)	upex-middle

Note that the replies from MyMDC were intercepted to change the beamtime dates and proposal status.

Tests were added to check for various scenarios.
