Inject GerritRemoteReader instance

When a manifest contains a project in a second host, the manifest parser
generates a correct .gitmodules but the GerritRemoteReader ignores the
host and tries to read the sha1 of the submodule from <this
host>/<project>. In some cases this produces an inconsistent
superproject: the .gitmodules points to a repo but the SHA1 in the
gitlink doesn't exist there.

Cross-host is a feature of the backend, the default implementation
should not count on it.

Make the GerritRemoteReader injectable, so providers can use a
cross-host implementation if supported in their platform.
