closes #3919

Describe your changes

In the start.go file, I introduced a new command, flyte single start, which is used to start a Flyte cluster locally. This command includes the following key changes:

• The startCmd variable is defined to create a new Cobra command named "start." It has a brief description indicating its purpose.
• Inside the RunE function of this command, an error group (errgroup) is created, and the childCtx context is derived from the parent context (ctx).
• You access the configuration using the GetConfig() function to retrieve the configuration settings for different components such as Admin, Propeller, and DataCatalog.
• Three different components are started in parallel if they are not explicitly disabled in the configuration:
• Admin: The Flyte Admin server, including database migrations and seeding of default projects.
• Propeller: The Flyte Propeller component, including its controller and webhook server.
• DataCatalog: The Flyte DataCatalog component, including database migrations.
• The errgroup (g) is used to coordinate the start of these components in parallel.
• Finally, the function waits for all the components to complete by calling g.Wait().

This change allows users to conveniently start a Flyte cluster locally using a single command while providing the flexibility to disable specific components as needed.
