IMPALA-7734: Catalog and Statestore memz page shows useless memory
The MemTracker is removed from StatestoreD main and CatalogD main as
it is not used. The /memz page related metrics are refactored to a
a separate file. When the MemTracker is not available during callback
initialization it should not be part of the callback either. Therefore,
when MemTracker is not part of the callback it is not displayed.
Before/after pictures of the /memz page can be found in the Jira.

> If you look at catalogd memz, e.g. at localhost:25020/memz, it has a bogus
> breakdown. The catalogd does not use the MemTracker infrastructure since the
> vast majority of it's memory consumption is in the JVM.
> {noformat}
> Breakdown
> : Total=0 Peak=0
> Untracked Memory: Total=0
> {noformat}
> Reported by [~alanj_impala_5a78]
> Update: It is the same for statestored as well and apart from "breakdown"
> section, the "Memory consumption / limit" part is also redundant. Should
> remove both parts from the memz pages of both daemons
