[Kimchi-devel] [PATCH V2 1/2] Fix debug report naming problem (backend)

[Rodrigo Trujillo]

The tool sosreport only accepts letters, digits and hyphen in the name
of the report, non alphanumeric characteres are removed from the file
name and then Kimchi is not able to find the file.

This patch fixes the problem in the backend, adding json schema
verification.

Implement name generation in backend
