Use editable install of datadog_checks_base for tests

[ofek]

Motivation

• Always use the version of datadog_checks_base on your branch
• pip install of a directory is super slow pypa/pip#2195

Additional Notes

Script (Python 3 only)

Since this is everywhere, shouldn't we create a constant for datadog_checks and make it part of the "template" for the setup.py file?
Also, would it be possible to factorize the deps block instead of doing so many copy past (maybe with a global tox.ini file)?

There is odd behavior here for some checks, sometimes, on Python 2.

pypa/setuptools#230
pypa/pip#3
