stephane 5644b68a54 Refactor env-setup.sh
env-setup.sh got kind of unwieldy and out of sync
with itself. Refactor so we have relatively consistent
package lists, installation checks, etc. for each OS family.
This should be easier to maintain than what we have now
as it's easier to see where additional requirements should
be added.

# other python requirements. pip breakages can seriously impact us,
# so we've chosen to install/upgrade pip here rather than in
# requirements (which are synced automatically from the global ones)
# so we can quickly and easily adjust version parameters.
# See bug 1536627.

# won't work. Remove the alternatives. This is due to ansible's
