Remove pip and pip-tools from requirements

[fievelk]

Adding these two packages to the requirements is considered to be unsafe, and it's also generating errors/warnings because of incompatibilities with some of our dependencies. Updating pip and pip-tools should be manually done by the dev.

• remove pip and pip-tools from explicit requirements
• re-compile requirements (using pip-compile from pip-tools)

Why are these rendered like this? I recall that this is not the first time, do you have any clue?

New pip-tools version AFAIK

@Hassan754 @spyrostz exactly: jazzband/pip-tools#1237. This is done to avoid git conflicts.
