Behavior change: to_container(..., enum_to_str=True) to convert both keys and values

[Jasha10]

$ cat tmp.py
from enum import Enum
from omegaconf import OmegaConf


class Color(Enum):
    RED = 1
    BLUE = 2


conf = OmegaConf.create({Color.RED: Color.BLUE})
print(OmegaConf.to_container(conf, enum_to_str=True))

$ python tmp.py
{<Color.RED: 1>: 'BLUE'}

Desired output is for both key and value to be converted when enum_to_str is set to True:

{'RED': 'BLUE'}
