Fature: Add command to list tasks

Currently to know the tasks that are deployed in the environment the user needs to list the S3 bucket and browse in the files to see details (ie. cron expresion).

Proposed:
Add new command to list tasks deployed in the S3 bucket and detailed info in a crontab manner:

(cron expresion) (type) (name)
```
0 * * * *   lambda   run-etl-process-prod
0 9 * * *   queue    my-scheduler-queue
```
