Can we have factory features in install_fixtures not just install_fixture

[rahulramakrishnan]

Currently if we want to override a field for a fixture,
we have to use install_fixture like so

self.install_fixture('foo', overrides={'a': 'baz'})
self.install_fixtures((
'foo',
'bar',
'baz'
))

however, the ability to do this inline would be nice:

self.install_fixtures((
'foo',
'bar',
'baz',
('foo', overrides={'a': 'baz'})
))

The problem with this is that fixtures might be different types. foo and bar might be two different models.

It seems cleaner and more intuitive to do a loop:

for name in ('foo', 'bar'):
    self.install_fixture(name, overrides={'a': 'baz'})
