In such cases when api server is overloaded and returns a lot of 429 (too many requests) errors - binding may take a lot of time to succeed due to retry policy implemented in rest client. In such events cache ttl for assumed pods wasn't big enough. In order to minimize probability of such errors ttl for assumed pods will be counted from the time when binding for particular pod is finished (either with error or success) Change-Id: Ib0122f8a76dc57c82f2c7c52497aad1bdd8be411
