multi: Remove high card keys for payment metrics

[yondonfu]

What does this pull request do? Explain your changes. (required)

Remove high cardinality keys i.e. recipient/sender and manifestID from payment/ticket metrics. Now, only aggregate payment/ticket metrics are reported and there is no metrics reporting on a per recipient/sender or manifestID basis.

Prometheus doesn't like high cardinality keys/labels so when using Grafana to load Prometheus data a dashboard that uses payment/ticket metrics the dashboard might be really slow to render or may even cause the Grafana app to crash as reported in #1763.

Specific updates (required)

• Remove high cardinality keys from payment/metrics reporting functions in monitor package
• Update arguments passed into payment/metrics reporting function calls in other packages

How did you test each of these updates (required)

TBD.
