Resolve environment variable in google drive credential path

[ClementHector]

Brief description

Allow resolving a path with an environment variable in gdrive credentials.
For example:
if OpenPype is installed in path/to/OP and setting project_settings/global/sync_server/sites/gdrive/credentials_url is {OPENPYPE_ROOT}/path/to/cred_file.json will give /path/to/OP/path/to/cred_file.json

I don't think acre merge should be used for this. I understand that part of the logic is same but acre is meant for environment variables and merges all same values together which may be dangerous in this case (calling the acre.merge).

Function which would only parse the dictionary as is and tries to fill env values in, is the way == skip the merge. Something like this:

def prepare_platform_values(data, env=None):
    if env is None:
        env = os.environ
    env_copy = env.copy()
    parsed_data = acre.parse(data)
    for key in tuple(parsed_data.keys()):
        value = parsed_data[key]
        try:
            parsed_data[key] = value.format(**env_copy)
        except KeyError, ValueError:
            pass
   return parsed_data

@iLLiCiTiT isn't that just doing acre.prepare and acre.compute? :)

I ain't find acre.prepare

I didn't think it was a problem because the envrionment is copy and not reinject at the end. Using accre made sense to me, I will do a simple format.

There is possibility that you'll have environment with name EXAMPLE and will have key stored under EXAMPLE and they'll be merged using os.pathsep which is not expected. In other words the merge does more than should. The formatting part is actually side effect of merge.

isn't that just doing acre.prepare and acre.compute

I would say that compute is for this case more complicated, but yes.

Works.
