Enable proactive renewal of Managed Identity tokens

[scottaddie]

Intro:
Refreshing the tokens with half lifetime would improve resiliency for clients if there's an ESTS outage while fetching a token.

Acceptance Criteria:
All MSI tokens are refreshed at least half lifetime token request is made after half lifetime

MSI has token lifetime of 24 hours. Refresh the tokens if refresh_in is passed from ESTS or at half lifetime if refresh_in isn't passed. For tokens which have lifetime of less than 2 hours, there are no changes to be made.
