Fixes#8316
* Don't use test classes to group tests
* only use formatting for parts of the string that change
* Flake 8 column limit
* Make the modification of the estimator more explicit in the tests
* As suggested in code review, prefer formatting over two literals
* Also assert, that __setstate__ overwriting works in mixin
* Remove cache property
* Use assertion functions from sklearn.utils.testing
* remove the protocol argument in tests
* Rename attributes to better convey their purpose
* Revert change of module in TreeNoVersion
* Adhere to column-limit
* changelog entry
* Fix commit message
* Remove Python 2.6 support
Some details about some slightly orthogonal changes:
* Note about cheking safely for nan is likely not valid any more (commit
introducing it is c80ca91b)
* scipy.linalg.qr econ parameter removed since scipy 0.9 in favour of
mode='economic'
* Remove unnecessary libgfortran in conda create command
* Putative fix by setting the random seed
* Revert unintended change
* Reinstate previous logic for checking for NaNs
* Reinstate change in error message
Error messages from Python 2.7 assertRegexp does not contain the
function name, in contrast with Python 3 assertRegex
* BF: issue 5522 (cloning objects with pandas.Dataframe attributes)
* super conservative fix, pending GP and VBGMM fixes.
* TST improved test for df param
* add deprecation warning, add whatsnew entry
* fixed place of deprecation warning, added test for deprecation warning.

FIX/ENH/TST Addressing the final reviews
COSMIT c --> count
FIX/TST make check_cv raise ValueError for string cv value
TST nested cv (gs inside cross_val_score) works for diff cvs
FIX/ENH Raise ValueError when labels is None for label based cvs;
TST if labels is being passed correctly to the cv and that the
ValueError is being propagated to the cross_val_score/predict and grid
search
FIX pass labels to cross_val_score
FIX use make_classification
DOC Add Returns; COSMIT Remove scaffolding
TST add a test to check the _build_repr helper
REVERT the old GS/RS should also be tested by the common tests.
