This change sets up a usage counter for productivity analytics feature.

Code Review Usage Ping for Create SMAU

This removes the group_overview_security_dashboard feature flag

This extends our existing `Gitlab::UsageDataCounters::NoteCounter` to
also count notes on commits and merge requests

This change adds a new counter 'cycle_analytics_views' to the usage data
metrics to count the page views for cycle analytics show page.

Source Code Usage Ping for Create SMAU

Generalize wiki page counter for other page types to extend to.

- the typo in this factory name was precluding us from properly
creating dynamic code to remove duplciation.

Added usage ping counter when the user makes
a search through the navbar search component.

This adds a counter to count page creation, which is reflected in the
usage-data we collect.

The number created is stored in Redis, avoiding DB access.

The actions tracked in the web IDE are:
- creation of commits
- creation of merge requests
- projects loaded

- use predefined factories when creating
projects with services
- remove unnecessary arguments

Gitaly data wasn't available to the team, an this change is a first
iteration towards understanding what data we need and how to interpret
it. Later more values will be added.

For now the most important thing is the filesystem String Array, as that
includes data on ext4 exposure and NFS.

PoolRepository is a relatively new model of which the counts could help
to further determine the priority of new features. Also gives some
insight into the number of forks customers have.

This adds influxdb_metrics_enabled and prometheus_metrics_enabled to
usage ping.

user_preferences key is includes into system usage
data only if group_overview_security_dashboard
feature flag is enabled; see
https://gitlab.com/gitlab-org/gitlab-ee/issues/7048

Implements UsageCounters model to track feature usage counters
and makes easy to extend for future counters

We also try to unify the way we setup OmniAuth, and how we check
if it's enabled or not.
