RUMM-2353: Report frustration count on views

[0xnm]

What does this PR do?

This change adds view.frustration.count data point, which is a total count of the all the frustrations happened in all the nested actions.

To support this I've changed EventType enum to the sealed class, so it is possible to send a payload on the data storage notification loopback.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Make sure you discussed the feature or bugfix with the maintaining team in an Issue
• Make sure each commit and the PR mention the Issue number (cf the CONTRIBUTING doc)
