HDDS-11586. Remove duplicate OzoneManagerProtocolServerSideTranslatorPB#OM_REQUESTS_PACKAGE

What changes were proposed in this pull request?

The same validation package is defined in OzoneManagerProtocolServerSideTranslatorPB and RequestValidations, so you only need to keep one of them.

Thanks.

I don't really think these are duplicates. RequestValidations provides a default value for convenience. OzoneManagerProtocolServerSideTranslatorPB sets explicit value for safety. The two values happen to be the same.

Thanks @adoroszlai for the comment and review.
Because the default DEFAULT_PACKAGE has been defined in RequestValidations, and the DEFAULT_PACKAGE has been assigned by default in RequestValidations#validationsPackageName. Therefore, I think it is not necessary to define the same value in OzoneManagerProtocolServerSideTranslatorPB, which seems a bit redundant.

......
private static final String DEFAULT_PACKAGE = "org.apache.hadoop.ozone";
private String validationsPackageName = DEFAULT_PACKAGE;
......

If it is for security reasons, I think it is okay not to modify it.
