OAuth token management

• This is a workaround to use multiple oauth2 identities.
• appcfg.py offers either password auth or oauth2.
• If you use oauth2, you're resricted to just 1 identity – the file storing the information is hardcoded to ~/.appcfg_oauth2_tokens. (Ref: appengine_rpc_httplib2.py: HttpRpcServerOauth2)
• You can use --no_cookies to avoid using that single hardcoded path.
• But now you have to provide the refresh token as the --oauth2_refresh_token param. (I would much rather that it support the --passin param as used by the password option instead of having it show up in the argv.) Sigh.

Here's one approach toward managing it.

import keyring

# Store OAuth token for later use.
def save_oauth2_refresh_token(email, oauth2_refresh_token):
    keyring.set_password(
        "OAuth2 Refresh Token: " + email + ": AppengineLauncher",
        email,
        oauth2_refresh_token)


# Sample call.
import getpass
save_oauth2_refresh_token("email@....", getpass.getpass())


def get_oauth2_refresh_token(email):
    return keyring.get_password(
        "OAuth2 Refresh Token: " + email + ": AppengineLauncher",
        email)

And wrap the call to appcfg.py using get_oauth2_refresh_token to pass in the --oauth2_refresh_token param (remember to also pass in --oauth2, --no_cookies and --noauth_local_webserver)
