Implement configurable retry mechanism for cert verification methods

[litt3]

• This should be implemented in such a way that all methods on the CertVerifier can be optionally retried
• Retry should be time based
• Implementation should support infinite retry, AND no retry
• Consider creating a reusable utility, which could be leveraged in other cases where we would want this sort of configurability
• The changes for this issue will enable us to address the concerns brought up by @bxue-l2, regarding cert verification retries to be addressed
