We add this dependancy to thumbor for no use other than making an
import possible in one of the upcoming commits. Basically we wanted to
import LOCAL_UPLOADS_DIR from zproject.prod_settings or
zproject.dev_settings and prod_settings_template.py imports
django-auth-ldap (which depends on python-ldap and django).
This seems counterproductive, but it makes it possible for us to save
significant thumbor server startup time that would have been consumed
in `get-django-setting`, and once thumbor supports Python 3, we'll
probably be merging the virtualenvs anyway (in which case this change
would become a no-op).
This commit renames various source requirements files like `dev.txt`,
`mypy.txt` etc to `dev.in`, `mypy.in` etc and various locked requirements
files like `dev_lock.txt`, `mypy_lock.txt` etc to `dev.txt`, `mypy.txt`
etc. This will help in emphasizing to the user that *.in are actually
input to `update-locked-requirements` tool which should be run after
updating any of these.
In this commit we add new dependencies needed for running thumbor.
Also we add the script for creating the virtual environment ready
for thumbor.
Note: Thumbor will use python2 and thus have different virtualenv
dedicated to it.
Credits to @TigorC and @joshland as well for there work on this.
