Send Telemetry metrics on OADP

We will want to establish some basic metrics we can report back to Telemetry.

Let's consider:

• Operator installs
• Backups, created, success, error
• Restores created, success, error

Below is some background info from MTC when we added Telemetry support that may help

See:  https://github.com/konveyor/metrics-queries/blob/master/README.md

• MTC - active customers from telemetry
• Migration Toolkit - telemetry usage tracking
• MIG - Metrics Info
