Develop Logs List UI

What does this MR do and why?

First iteration of the new Logs UI.

• Add LogsList component: fetches logs and renders the LogsTable component
• Add LogsTable component: renders the given table as a table. Log severity is rendered as a Label.
• Add fetchLogs API to client

Everything is behind :observability_logs feature flag

Mock up: gitlab-org/opstrace/opstrace#2611

Closes gitlab-org/opstrace/opstrace#2645 (closed)

Depends on Scaffold Logs UI feature (frontend) (!142990 - merged) and Scaffold Observability Logs feature (backend) (!142989 - merged)
