User Story (Required on creation):

As a EE User i want to be able to easily report my metrics to Camunda. Currently the metrics in Camunda are differently named as the metrics defined in the contract (New contract for the new license model defining TU, DI, PI). 

Functional Requirements (Required before implementation):

As a EE User i want to be able to access the metrics named as in the contract via:

• Cockpit,
• REST,
• Telemetry
• Database query

The metrics name should be adopted as follows

• RPI (root process instances) -> PI (process instances)
• EDI (executed decision instances) -> DI (decision instances)
• UTW (unique task workers) -> TW (task workers)

Technical Requirements (Required before implementation):

• docs are updated: https://docs.camunda.org/manual/7.16/user-guide/process-engine/metrics/
• public API behavior for existing metrics is not changed (https://docs.camunda.org/manual/7.16/introduction/public-api/#definition-of-public-api)

Limitations of Scope (Optional):

Hints (Optional):
