Firebase TransportError for repeated requests from the same user

[francbartoli]

Firebase sdk library seems to manage badly repeated requests:

    user = firebase_decode_handler(key)
  File "/home/gis/development/python/apps/gee-bridge/rest_auth_firebase/firebase_sdkadm.py", line 15, in firebase_decode_handler
    decoded_token = auth.verify_id_token(id_token, check_revoked=True)

It seems there should be no limitation on the number of requests

Upgrade to library 2.10+ and the problem seems solved
