Adding warning for uninstall --all while container runtime not running

[mcaupybugs]

Description

Added an else if condition to check the case when the dapr uninstall --all command is used but the container runtime is not running. In such a case, this code change will throw a warning stating that it could not remove the supporting containers.

Hey @shubham1172, I am not sure what E2E test should be written. Like I started to implement but after looking at the existing E2E tests I realized that each of those requires container runtime to be in the running state and is the first check done but my test case would require non-running container runtime. And if I try to manually give invalid container runtime using a --container-runtime flag then it will be blocked at the container-runtime validation step which is the IsValidContainerRuntime function and it checks if the runtime flag provided is either docker or podman. So not sure if i can even write E2E test for this scenario. please let me know wdyt

Hi @mcaupybugs, you could stop the docker daemon using os/exec. Did you try that? Whilst doing it, we need to make sure that no other test is running in parallel. Although at this point I feel that it's non-trivial, so I am creating a separate issue (https://github.com/dapr/cli/issues/1320) to track it and approving this PR. Thanks again for the PR! :)
