libweave: Retry failed RefreshAccessToken requests

During network outage, failed request to refresh access token may
result in failed XMPP connection which will not be re-established
until the next scheduled GCD server communication which may not happen
for as long as 30 minutes.

Added automatic retries with exponential backoff if the failure is
due to network connectivity.
