[FEATURE REQUEST] Create new task in CLI or asynqmon

Is your feature request related to a problem? Please describe. I'm always frustrated when trying to simulate task creation locally. There's no such feature for creating a new task in asynq tool CLI, nor in asynqmon.

Describe the solution you'd like Provide task creation via CLI or asynqmon to make it easier to debug locally. Example command in CLI, could be like this

asynq task enqueue --queue=example-queue --payload="{\"type\":\"UPDATE_VIEWER_COUNT\",\"stream_id\":83929120323,\"exec_at\":1663659030,\"interval\":300,\"exp_at\":1663662630}" 

Describe alternatives you've considered
