Migrate project VSA metrics to use dedicated project metrics endpoints

What does this MR do?

This MR updates the project level VSA metrics, currently the project VSA metrics differ to the metrics available at the group level, but as part of &5194 (closed) we want to adopt the same metrics measures and UI as the group level.

This MR:

• Adds project level VSA metrics requests, extracts group requests to the analytics_api module
• Updates the UI for project VSA metrics to match group level metrics
• Refactors the metrics.vue (renamed to value_stream_metrics) component and moves it to FOSS
• Updates the metrics component to take requests used as a prop, so we can reuse the component at the group level and project level (the metrics to be displayed and their config are returned from the API endpoints)
• Adds additional frontend fixtures to update the FOSS specs
