Wiki Usage Ping for Create SMAU

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.

Fix the project auto devops API

See merge request gitlab-org/gitlab-ce!30946

If `project_auto_devops.enabled` is nil for a project, when setting any
auto devops values via the API, we try to create a new row in the DB,
instead of re-using the existing one. This leads to the project_id
being set to nil, and the database `NOT NULL` constraint leading to a
500 response.

This commit resolves the issue by correctly detecting the presence of a
ProjectAutoDevops row and re-using it. Persistence is also moved away
from explicit `update!` calls and into relying on `autosave: true` on
the model.

Avoid increasing redis counters when usage_ping is disabled

See merge request gitlab-org/gitlab-ce!30949

If `GitalyClient#can_use_disk?` returned `false`, it was never cached
properly and led to excessive number of Gitaly calls. Instead of using
`cached_value.present?`, we need to check `cached_value.nil?`.
