Update git submodules

* Update docs/submodules/integration/test from branch 'master'
  to 7a61f04c8e4c1b0b7b55b8e88201ad0607490e26
  - Use -o MACs=hmac-sha1 for instance ssh connections

    It's not clear (to me) why we need this hmac-sha1 option,
    but our new APEX images need it to make our connectivity
    csit test cases work.

    Also, while debugging this I tweaked the timeout numbers
    to 5s for the initial ssh connection (from 10s) and 10s
    to get the prompt (from 30s). In the case of failures,
    having smaller values here will speed up the tests, and
    5s/10s seem reasonable enough anyway.
