Yeah, But I thought ECSchemanager can load configs from XML. When instantiating ECSchemaManager,
we can load required configs from edschema-def.xml file. If you are also thinking the similar
change then we can incorporate here itself. May be ECSchemaManager can take config from its
Ctor. BTW, I have no concern if we want to handle the improvements in followups.

> It's good to have a system default EC schema first with fixed values before we support
more schemas. This makes sense to resolve some dependencies before HDFS-7866 can be done in
whole. The default system schema is also needed anyhow essentially when admin just wants to
use it.
