Documentation - WorkspacePermissionDeniedException

[ganeshchand]

Scenario: A user is running dbcDeploy command against a cluster. The use either has No Permissions or Can Attach To cluster permission. The user tries to run dbcDeploy command and gets the following error: WorkspaceAclExceptions.WorkspacePermissionDeniedException: ganesh@databricks.com does not have Manage permissions on TestCluster. Please contact your administrator for access.

Cluster Access Control is available for Professional and Enterprise Tier Databricks customers. When When Cluster Access Control is enabled, user needs to get appropriate permissions from the cluster administrator. For dbcDeploy, user requires Can Manage cluster permissions.

Let me know if the above statement is accepted and I can send a pull request to update README.md
