debug flag to logging level flag

[scalp42]

Hi @someara

Currently the logging is hardcoded to debug which I think is due to the addition of the service_container recipe.

Unless I'm mistaken, the service_container recipe does not pass template variables, so I removed the unused debug_flag variable in the recipe.

TLDR:

• [x] swap "debug" flag for "logging_level" flag
• [x] logging level is set to info
• [x] set default['push_jobs']['logging_level'] in the attributes, default to info
• [x] less spam for all the hearbeats due to debug level
