Remove coglog analytics/telemetry package (#2690)
* Remove coglog analytics/telemetry package
The coglog package sent build and push duration analytics to
coglog.replicate.delivery. This removes the entire package and
all its usages from the codebase.
* Simplify Provider interface by removing PrePush
Now that coglog analytics have been removed, PrePush was a no-op for
both GenericProvider and ReplicateProvider. This removes:
- PrePush method from the Provider interface
- PrePush implementations from both providers
- BuildID and HTTPClient fields from PushOptions (only used for analytics)
- Related tests
