Relying on cache.get is not always safe

Also, move the complete component list from the index
to the Admin Guide.

Add new 'filter_objects_results' function to apply filters, e.g. from
--filter-by option to objects. Rename old 'parse_filters' function ,that
parsed filters to querytset arguments, to 'parse_queryset_filters.
The new function is currently unused.

Optimize server-list command by prefetching related fields if needed.

When --quiet flag is used, burnin will not produce a logging
file at all (neither will log to stdout). This flag is used
when we simple want to check if there are stale servers from
previous runs (we can do this based on burnin's exit status)
but we don't want to produce any log files.

Add the kamaki_version parameter to the ci config file.
Using this parameter the user can specify a version of kamaki
to be used (mostly by burnin).

Force the use of version 0.11next-1811-197b413 for kamaki,
as currently is the version that works with develop.

This testsuite is used to inspect and delete stale servers
(servers left from previous burnin runs).

Since each instance of the TestCase will only be used to run a single
test method (a new fixture is created for each test) the attributes can
not be saved in the class instances. Instead we use descriptors.
