Management command to remove a specific flag

[dancergraham]

A smaller scope than #492 - it would be nice to have a management command similar to --create to remove a flag
I suggest --delete

ahh sorry there is a separate command for this - I wonder whether this would be better as an alias or comment in the main django_waffle management command... It seems strange to have so many options under the main command and a separate command just for deleting.

Any opinions on adding aliases or --help doc comments ?

• waffle_flag --delete -> waffle-delete --flags
• waffle_switch --delete -> waffle-delete --switches
• waffle_sample --delete -> waffle-delete --samples
