Run python with jemalloc in containers

Browse Source 
jemalloc is apparently good with python memory according to

  https://zapier.com/engineering/celery-python-jemalloc/

Also, according to these graphs from Tobias:

  https://paste.pics/581cc286226407ab0be400b94951a7d9

it helps with the apparent memory leak seen in python3.6
and python3.7 with zuul.

There doesn't seem to be any downside to it, so install it
and enable it.
