release-21.1: workload/movr: add --multi-region and --survive settings

[otan]

Backport 1/1 commits from #65493.

/cc @cockroachdb/release

---

Release note (general change): Added multi-region workloads for
cockroach demo movr --geo-partitioned-replicas. Specifying
--multi-region allows for multi-region workloads, and specifying
--survive allows for surviving AZ or REGION failures.

I feel uncomfortable backporting this change until we have at least some testing around it. Can we address that before we proceed on backporting?

the existing tests for these heavily flake on CI, probably because the machine is hammered. i will not have time to investigate this (we all remember what happened last time i dove into a cli issue ;P)

let's see if #65687 deflakes partitioning, if so i have a path forward to adding the tests without flaking.

[ajstorm]

SGTM. I'll stay tuned. Poke again when you want me to have another look.
