Update git submodules

* Update kolla-ansible from branch 'master'
  to 4da849def43c5763ec48886d94f33b4fe1af7948
  - Merge "Add support for libvirt swtpm (vTPM) configuration."
  - Add support for libvirt swtpm (vTPM) configuration.

    Since both nova-compute and nova-libvirt Kolla images have swtpm
    packages installed [1], it is possible to configure vTPM for libvirt
    instances. This patch adds support for such configuration in
    kolla-ansible.
