[PATCH 14/14] report: allow test runners to inject arbitrary values

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

Per Ted's request, add to the test section reporting code the ability
for test runners to point to a file containing colon-separated key value
pairs.  These key value pairs will be recorded in the report file as
extra properties.

    this option is supported for all filesystems currently only -overlay is
    expected to run without issues. For other filesystems additional patches
    and fixes to the test suite might be needed.

+   Whitespace surrounding the colon will be removed.
