Prior to this change, we setup our feed variant query to have a cached
randomization seed. For a given user this seed is cached for 15
minutes. The goal of this is to provide mostly consistent sort orders
on the feed articles during that 15 minute window.
With this change, we allow for a feed variant to say ignore the cached
seed and generate a new one for this call.
I have also added explicit settings to each of the feed variants to
reflect our desired intentions for those features.

* Adding new relevancy lever for privileged reactions
This PR includes four changes:
1. Renaming the variant to remove Jennie's name
2. Starting a new experiment
3. Adding a new relevancy lever
4. Adding a new variant that uses the relevancy lever
1 and 2 is somewhat straight-forward.
For 3, we're looking at having a total of 5 "slots" for privileged user
reactions. Hence the four boundary values.
For 4, we're configuring the granular levers with the following:
- `[-∞..-5)` should have a 0.05
- `[-5..0)` should have a 0.5
- `[0..5)` should have a 0.9
- `[5..10)` should have a 0.98
- `[10..∞)` should have a 1.0
The 20220509-variant.json is a copy of 20220422-variant.json but
replaces the `privileged_user_reaction` lever with the
`privileged_user_reaction_granular` lever.
Below is the diff to highlight the similarities and differences between
the two variants.
