Update git submodules

* Update docs/submodules/fuel from branch 'stable/fraser'
  - Merge "[reclass] Parameterize tenant VLAN ranges" into stable/fraser
  - [reclass] Parameterize tenant VLAN ranges

    Instead of hardcoding the VLAN ranges in reclass, read them from IDF.
    This is required when VLAN segmentation is used instead of VXLAN, as
    lab switches should be configured appropiately (e.g. Armband PODs use
    VLANs 2000+ instead of 1000-1030).
