Metrics component of #1744.
Extends upstream metrics additions from aws/smithy-go#536 with the following instruments (and their dimensions):
client.call.errors
- number of errors encountered (service, operation, error type)client.call.attempts
- number of attempts made (service, operation)client.call.attempt_duration
- time span for an entire attempt (service, operation)This is not the final merge before release, as some minor tweaks need to be made to some of the component names to align with our internal guidelines.
