Use custom Jinja2 filters

[berti-peitz]

Hi,
is there any chance to use custom Jinja2 filters with Dynaconf.
In fact I have an extended Jinja2 Environment object, but how to pass to Dynaconf?

import jinja2


def rfc1123(string):
    return re.sub(r'[^a-zA-Z0-9]+', '-', string).lower()


env = jinja2.Environment()
env.filters['rfc1123'] = rfc1123

# how to proceed?

Never tried but may work.

from dynaconf import Dynaconf
from dynaconf.utils.parse_conf import jinja_env
jinja_env.filters['rfc1123'] = rfc1123


settings = Dynaconf(...)

Maybe we need to provide a better standard way to do that.
