Please check https://issues.apache.org/jira/browse/IGNITE-20187 for more
context, that is about catching-up assignments.pending meta storage keys,
whether given one is about catching-up its triggers:
* Replica factor updates.
* Partitions count updates. Immutable for now.
* Data nodes updates.
* Replica storage addition/removal. !By the way, is it possible to remove
replica storage.
For all aforementioned cases, it's required to update distributed assignments
pending (planned) keys if it's not yet done. And the only difficulty here is
precisely in understanding whether this was done or not.

the current triggers state.
