[RFC] Add dotenv loader to allow multiple dotenv files

[mazlum]

I love dynaconf. It doesn't support multiple dotenv. I think it should support multiple dotenv.

for example;

settings = Dynaconf(
    dotnev_path=[str(BASE_DIR / "envs")],
    settings_files=[".env", ".secret.env"],
)

I think it is a good idea to add a .env loader to handle .env extension files.

The workaround for it is

from dynaconf import Dynaconf
from dynaconf.utils.parse_conf import parse_conf_data
from dynaconf.vendor.dotenv import dotenv_values

envvar_prefix = "MYAPP"
settings = Dynaconf(envvar_prefix=envvar_prefix)

data = {
        k[len(envvar_prefix):]: parse_conf_data(v, tomlfy=True, box_settings=settings)
        for k, v in dotenv_values(".secret.env").items()
        if k.startswith(envvar_prefix)
}

settings.update(data)
