HDDS-2064. OzoneManagerRatisServer#newOMRatisServer throws NPE when OM HA is
configured incorrectly
URL: https://github.com/apache/hadoop/pull/1398
The WIP patch can prevent NPE in `TestOzoneManagerConfiguration` unit test
`testWrongConfigurationNoOMNodes` and `testWrongConfigurationNoOMAddrs`. But it
fails `testWrongConfiguration` and `testMultipleOMServiceIds`.
I might need to place the fix logic in other places instead of
`OzoneManager` to pass the other unit tests without modifying them? Please
advice.

> OM will NPE and crash when `ozone.om.service.ids=id1,id2` is configured but
> `ozone.om.nodes.id1` doesn't exist; or `ozone.om.address.id1.omX` doesn't
> exist.
> Root cause:
> `OzoneManager#loadOMHAConfigs()` didn't check the case where `found == 0`.
> This happens when local OM doesn't match any `ozone.om.address.idX.omX` in
> the config.
