Zeyi (Rice) Fan 92f6f35e7a mark all tests requiring Python 2
Summary:
This diff marks **ALL** mercurial tests requiring Python 2 feature.

After you fixes some tests, simply remove the `py2` feature requirement and that tests will be continuously run after your diff is landed.

To bypass this feature requirement, run the tests command with `HGTEST_FORCE_PY2=1`. For example:

```
HGTEST_FORCE_PY2=1 buck test //eden/scm/tests:hg_run_tests
```

or

```
HGTEST_FORCE_PY2=1 python run-tests.py
```

----

Basically this diff are created with the following commands:

```
$ sed -i 's/import feature\(.*\)$/import feature\1\n\nfeature.require(["py2"])/' test-*-t.py
$ sed -i '1s/^/#require py2\n/' test-*.t
$ ls | grep -P "^test.*(?<\!-t)\.py$" > list && vim -p $(cat list)
# manually adding feature requires for these Python tests.
```

(Note: this ignores all push blocking failures!)
