HDDS-4117. Normalize Keypath for listKeys.

[bharatviswa504]

What changes were proposed in this pull request?

Normalize Keypath for listKeys.
When ozone.om.enable.filesystem.paths, OM normalizes path, and stores the Keyname in the OM DB KeyTable.

When listKeys uses given keyName(not normalized key path) as prefix and Starkey the list-keys will return an empty results.

Similar to HDDS-4102, we should normalize Starkey and keyPrefix.

Note:
This PR is based on top of #1328
To get CI, posted a PR with both fixes included.
