Level of logging messages in case of resource failure

[hackermd]

When job submission fails due to problems with backend resources the logging messages are not very helpful at ERROR level:

ERROR    | gc3.gc3libs                              | Invalid state ''NEW'' returned by task 2.
INFO     | gc3.gc3libs                              | Rejecting resource 'localhost': requested more memory (3500MB) that resource provides (2.04678e+06KiB, 2.04678e+06KiB per CPU core)
WARNING  | gc3.gc3libs                              | No compatible resources for task '3' - cannot submit it

Since the GC3Pie logger is very chatty, I like to set it to ERROR. Upon resource failure, I would expect a message at this level.

Upon resource failure, I would expect a message at this level.

Which messages of the 3 you posted should get "promoted"?

All of them should be ERROR messages in my opion. The Rejecting resource ... message would be particularly useful at ERROR level, since it would point users in the right direction without having to increase logging verbosity.
