[tsv1]

This PR introduces the TipAdviserPlugin, which enhances the user experience by analyzing command-line arguments to provide actionable tips for optimizing test execution.

Key Features:

• The plugin generates helpful tips based on command-line arguments like --repeats, --fail-fast, and --fixed-seed.
• Tips are displayed in the summary report after test execution, offering guidance on improving testing practices.
• The plugin behavior is controlled through the TipAdviser configuration class, with an option to enable or disable tips (show_tips).

Plugin Highlights:

• Encourages best practices, such as using --fixed-seed for consistent results in repeated test runs or enabling --fail-fast-on-repeat for faster feedback in failing scenarios.
• Easily disabled via the vedro plugin disable vedro.plugins.tip_adviser command.
