feat: Round Robin Weights

[CarinaWolli]

What does this PR do?

Adds weights to round robin alogirthm. When weights are enabled each host has 100% as the default weight. That means that ideally, all hosts end up with the same amount of bookings. If weights are enabled, priorities are only taken into account when more than one host is selected by the getUsersBasedOnWeights function.

Weights enabled:

Weights disabled:

Set weight:

• Fixes [CAL-3869] Round Robin Weights #15340
• Fixes CAL-3869

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected)
• I have added a Docs Add Round Robin weights docs#101
• I have added or modified automated tests that prove my fix is effective or that my feature works (PRs might be rejected if logical changes are not properly tested)

How should this be tested?

• Create RR event type and enable weights
• test different weights and priority settings
• test adding new hosts when bookings already exists and see if weightAdjustment was correctly saved
