ccm-fetch to support downloading test profiles

[msmark]

As per quattor/aquilon#34, ccm-fetch will need to support the -t flag which will instead cause a test profile to be collected and downloaded into the test profile cache, instead of a live profile.

The following new command-line arguments and corresponding entries will be added to /etc/ccm.conf:

Option	Description
test_profile	URL of test profile to fetch if launched with -t
test_profile_failover	URL of test profile to fetch if primary URL is broken, similar to profile_failover.
cache_test_root	Location of the root for test profiles. Defaults to /var/lib/ccm-test.

@msmark no need for failover the test_profile should support a list of urls to try in order (i think that regular profile already does that, and that profile_failover is legacy)

[stdweird]

@msmark or not, i must be confused with some other code. feel free to open an issue for such support

[msmark]

@stdweird would I need a new issue for that? Shouldn't it all be covered by this issue?

[stdweird]

no real preference 😄

Ok I've updated the description in this issue.
