When a metric cannot be loaded, our frontend would stop after 3 tries
if a metric loading failed. This change removes the retry count and
replaces it with a long timeout.

This is done by grouping all dashboard metrics requests in a
Promise.all and by prompting the user when any of them fails.

The other metrics can still load, so specs are added to emulate
these condition when a single metric fails have been updated.

Fix project creation with templates using /projects/user/:id API

Closes #37004

See merge request gitlab-org/gitlab!20590

Previously creation with an instance or group template with POST
`/api/v4/projects worked`, but `/api/v4/projects/user/:id` did not
because the latter did not accept the `use_custom_templates` parameter
due to an oversight.

This commit fixes this by adding the `optional_create_project_params`
Grape API and add tests for project creation via the user endpoint.
