create tenant user command
Revert "create tenant user command"

This reverts commit 292dc515dccf1a7327bae96c2088aca10f94bd21.
tenant_command wrapper around default commands
option to specify --tenant arg
remove unused code
override create_parser to allow custom args

this allows you to run custom stuff like:

python manage.py tenant_command createsuperuser --foo=bar

without optparse.OptionParser.disable_interspersed_args(),
the above call would fail because --foo is not explicitely
listed as a valid option in tenant_command
documentation for tenant_command
get options from parent command gracefully
don't need conflict_handler, or duplicate opt
should be --schema, not --tenant
Merge pull request #66 from MontmereLimited/create-tenant-user

added tenant_command, wrapper for django commands
