"readTree" has been implemented for the "GerritUrlReader". Gerrit have
a REST API's to download repo contents but there are a number of
limitations that makes it unusable.
This implementation works as follows:
* The project and branch is parsed from the url.
* The current revision is fetched from the Gerrit REST API.
* The revision string is used as "etag".
* If the etag has changed a temporary directory is created.
* The project is cloned to the temporary directory.
* The cloned content is read into a "Readable Stream".
* The temporary directory is removed.
* "readTree" returns a response using "fromTarArchive" as read from the
temporary directory.
Also added an option to specify the base "cloneUrl" has been added to the
gerrit integration config.
