Description

1.  User should be allowed to create a compute if:

• Notebook has not any compute 
• Notebook has compute in 'failed' status
• Notebook has compute in 'terminated' status

2.  User is not allowed to create a compute if:

• Notebook has compute in 'running' status
• Notebook has compute in 'creating' status
• Notebook has compute in 'configuring' status
• Notebook has compute in 'reconfiguring' status
• Notebook has compute in 'stopping' status
• Notebook has compute in 'stopped status
• Notebook has compute in 'starting' status
• Notebook has compute in 'terminating' status

3.  If user is not allowed to create a compute 'Add compute' action should be disabled. If user hovers the mouse disabled 'Add compute' action a hint should show up: 'Only one compute can be associated with analytical tool at a time' 

4.  Prevent context menu for Web terminal 

5.  Assign appropriate name  for hint during copy links: for notebooks/clusters
