29106	Make manage.py test display the test tags that are in use	Rich Jones	Sanyam Khurana	"_This ticket is part of the Django Test Output Beautification initiative: https://code.djangoproject.com/ticket/29101_

Django 1.10 introduced a wonderful new feature, test tagging, which allows the user running tests to control which tests are included and excluded in a test execution. This is particularly handy in complicated and conditional continuous integration setups, which may require lots of different tag inclusions and exclusions.

The annoying part is that the default test output, and even the test output with higher verbosity levels, never displays which tests are excluded or included. 

I'd be great if this information could be displayed in three ways during a test execution: Once during initialization, to show which tags were included or excluded, once for each test as it is skipped, and once during the final tally.

So, at the beginning:

{{{
System check identified no issues (0 silenced).
Running tests, excluding [slow, veryslow].
}}}

For each test skipped:
{{{
========================
Testing 'test_good_file_grouping'
(data_refinery_workers.downloaders.test_transcriptome_index.DownloadTranscriptomeIndexTestCase)
_Makes sure that proper file group runs the pipeline._
-----------------------------------------------------
...
Ok!

========================
Skipping 'test_good_file_grouping'
(data_refinery_workers.downloaders.test_transcriptome_index.DownloadTranscriptomeIndexTestCase)
[veryslow]
-----------------------------------------------------

}}}

And finally, at the end:
{{{
----------------------------------------------------------------------
Ran 38 tests in 34.808s. Skipped 4 tests.
}}}

This should work appropriately for all of the different tag-related test arguments.

It'd also be nice if this test output was appropriately colorized.
