Add wrapper functions for telemetry & logging

[tnorling]

• Introduces invoke and invokeAsync helper functions to wrap APIs with telemetry measurements and trace logging.
• Adds perf measurements for ssoSilent/iframed flows
• Moves httpVerToken and refreshTokenSize to more central place right after POST
• Remove httpVerAuthority is it represents the same thing as httpVerToken but with a different name

Pros

• Makes it easier and less verbose to add logging & take perf measurements
• In theory should be less expensive from a package size perspective

Cons

• Makes code a bit harder to read
• If a function is called from multiple places each callsite must wrap the function (in contrast to being baked in today)

Let us track the user experience with a separate PR, approving as is. This is great improvement over redundant code.

[peterzenz]

Definitely a nice readability and maintenance improvement. Thanks.

Did you intend to remove this logger line as well?

[tnorling]

Yes, the invoke functions will handle logging start/end messages as well
