* Improved `describe-tenants` command, added ability to show parent tenant for the linked tenant.
* Added validation for allowed values of `cloud-list` parameter for `publish-service` command.
* The `run-instance` command has the following changes:
* The command is now working via the approval process. If instance-related quotas are depleted,
the instances will require a tenant-manager approval to be run. The approvals are based on notifications.
* Added a new `additional-storage` parameter.
* The output is changed. Now, it shows a status of the processed run-instance request and a details message.
* Replaced the `tenant-name` parameter with the `tenant-group` for `hourly-report`, `resource-report`, `subtotal-report` and `total-report` commands.
