As with auto-migration, this may be set either with a flag or a config
option. This means that NoteDbMigrator now has to modify multiple
"control" flags in the config that are not directly related to the
migration state.
Increase the heap size of the standalone tests, as it would otherwise
fail under bazel with "GC overhead limit exceeded". This implies there
is some kind of leak in the standalone sever test setup, but debugging
that is beyond the scope of this change.
