Migrate epic events to internal events: vol.4 - epic issues events

What does this MR do and why?

Related to #421593 (closed)

Migrate some of the redis_hll_counters.epics_usage.epics_usage_total_unique_counts_monthly event's sub-events to Internal Events API.

Script used to update the files:

class DebugGenerator < Gitlab::Analytics::InternalEventsGenerator source_root File.expand_path('generator_templates/gitlab_internal_events', __dir__)

def create_metric_file validate!

template "event_definition.yml",
  event_file_path(event),
  options.fetch(:event_desc)

end

def milestone "16.5" end end

Before	After

How to set up and validate locally

1. Enable snowplow micro
2. Trigger any of the events migrated here:

• add an issue to an epic
• remove an issue from an epic
• move an epic's issue into a different project
• change epic's parent or children epics
• close an epic
• reopen an epic
• promote an issue to epic

3. Make sure that the events have been triggered with content as per their new event definition files [eg. - category sent as InternalEventTracking] on the http://localhost:9091/micro/good snowplow micro endpoint.
