[Front-end]: Do not allow to restart provserv if one of resource is in processing stage

 Do not allow to restart provserv is any instance is in status:

• Creating
• Configuring
• Reconfiguring
• Creating image
• Stopping
• Starting
• Terminating

  Status	Notebook	Cluster	project (Edge node)
  Creating	+	+	+
  Configuring	+	+	-
  Reconfiguring	+	+	-
  Creating image	+	-	-
  Stopping	+	+	+
  Starting	+	+	+
  Terminating	+	+	+

Confirmation message shows up: 

'Oops!
 Can not restart provisioning because one of resource is in processing stage'

If restart provserv together with other service:

'Oops! Can not restart provisioning because one of resource is in processing stage'
 
Success! <Service_name> restarting started! 

Do it as it is implemented for project management.

Investigate what option should we choose: 
vvitanska, I investigated these two options, and it will be better to implement the second one.

1. Show information message after hitting restart button
2. Show information message on confirmation dialog before hitting restart button
