[vinokurig]

Signed-off-by: Igor Vinokur ivinokur@redhat.com

What does this PR do?

Fix Gitlab API raw file request.

• Pass the file path through the rawFileLocation function to avoid dot cut here:

  che-server/wsmaster/che-core-api-factory/src/main/java/org/eclipse/che/api/factory/server/scm/AuthorizingFileContentProvider.java

  Line 134 in 7878b13

  requestURL = remoteFactoryUrl.rawFileLocation(fileURL.replaceAll("^[/.]+", ""));

• Encode the .che/che-editor subpath to meet the Gitlab raw file request requirements.
