Update git submodules

* Update docs/submodules/pharos from branch 'master'
  - Merge "[fuel] IA: Add PXE/admin static IPs"
  - [fuel] IA: Add PXE/admin static IPs

    - check-jinja2.sh: Add template dir to include dirs;
    - add param definitions for PXE/admin static IP for each machine,
      moving MaaS DHCP range start after the new addresses, similar to
      public network;
    - drop 'opnfv_' prefix for compute parameters;
    - drop 'opnfv_jump_bridge_*' variables (deprecated);
    - drop 'opnfv_infra_maas_*' variables, handled directly in Fuel now;
    - add 'opnfv_net_*_mask' for all used networks in idf.net_config;
    - move all internal j2 variables to net_map.j2, so we can reuse them
      without pod_config;
    - refactor maas variables into a full `maas.region.machines` section
      when baremetal nodes are defined;
    - drop 'openstack_compute_*' reclass params in favor of direct
      expansion in reclass.storage definitions via j2 in Fuel@OPNFV;
    - add `net_macros.j2` for reclass linux.network reclass generation;
    - move all non-sensitive reclass parameters to Fuel@OPNFV;
