Add auto-retry on failed data function call in case of 401/500 error from statsvc

Problem:

If Statistics services returns 401 or 500 error (that happens often enough for our users), current behavior of Webplayer (10.3) is to just fail. Usually it is enough to do manual retry, or do analysis F5 refresh but that is inconvenient for the end users.

We do not have control over LDAP servers and their reliability and networking.

Solution:

I believe that a simple yet configurable automatic retry for the failed 401/500 requests to the Statistics server will not hurt here, webplayer gives up to early.

Result:

Users will not have to do workaround actions each time when LDAP auth will stutter due to LDAP server or network issues.
