Increased backoff time for repeated login attempts (#194)

The exponential backoff algorithm causes svc accounts
to be blocked after 11 login attempts.

To stop the accounts being blocked on a single set
of login attempts the backoff algorithm has been
slowed down.

At this stage, I am still unsure of the time limit
over which these 11 attempts will block an account.
This means that multiple retries of the entire CI pipeline may
still block a svc account.
