feature: merging a branch using `infrahubctl branch merge` should not timeout for branches with a lot of changes

Describe the Feature Request

When executing the command infrahubctl branch merge <branch> on a branch that has a large change compared to main, the command can timeout with the following error message Unable to read from 'http://localhost:8000/graphql/main'. (timeout: 120 sec).

Instead we should probably have similar behavior to how the schema load command works, where we can instruct the command to wait until the merge operation has succeeded or has failed.

Alternatively we could display a link to the user that can be opened in the browser to track the progress in Infrahub's UI.

Describe the Use Case

A time out returned by the infrahubctl merge <branch> operation might give the user the impression that something is wrong. We should find a better way to communicate to the user what is happening.

This is probably true for all tasks that can take a lot of time

• Branch rebase
• Branch merge
  and potentially more.

the good news is that everything we need to fix this should be in place now

• All GraphQL mutations should be able to return a task id instead of waiting for the task to complete
• The support for Task in the SDK has been introduced recently Add support for Tasks #276
