* chore: Support setting the value of `replica-priority`
This PR adds a small refactor to the way we set and get config names
which have dashes (`-`) and underscores (`_`).
Until now, words were separated by underscores because this is how our
flags library (absl) works. However, this is incompatible with Valkey,
which uses dashes as a word separator.
Once merged, we will support both underscores and dashes in config
names, but will only return the name with dashes. **This is a behavior
change**.
We're doing this in order to be compatible with `replica-priority` and
possibly other config names that Valkey uses.
* Flag restore
* normalize to '_'
* feat: implement CONFIG GET command
The command returns all the matched arguments and their current values.
In addition, this PR adds mutability semantics to each config - whether it can be
changed at runtime.
Fixes#1700
