Update git submodules

* Update docs/submodules/integration.git from branch 'master'
  to 7be9861d562abc762d65a4efd7cf49b493d70206
  - Exclude code location from code base URL

    Python method str.format allows easy templating using substitutions
    identified by braces ('{' and '}'). Using two levels of nested
    substitutions can be achieved by doubling braces ("{{" and "}}").

    Hound configuration creator script was supposed to use two levels of
    nested substitutions and still leave braced components within the
    templated string for further substitution by the Hound tool. This would
    require using multitude of braces which would decrease readability
    significantly.

    This is why code location template is appended to the code base URL at
    the latest.

    If there will be need for more levels of nested templates, this code
    shall be further refactored to use only named fields, str.format_map()
    (available in Python 3.2+) and SafeDict, e.g.

      >>> class SafeDict(dict):
      ...     def __missing__(self, key):
      ...         return '{' + key + '}'
      ...

    which would leave braced components within the processed template in
    case given key is missing.
