As a user I want to see more informative error message about failing instances on DLab UI, so that I do not need to go to SSN and look through logs.
- after notebook creation has failed user can see error message by clicking name notebook on 'resources list' page
- after computational resource creation has failed user can see error message by clicking name computational resourceon 'resources list' page
*** For example if user used all shapes limit of Amazon user can see the next error message: 'Shapes limit is exceeded'.
Content of error message should depend on error type.
