Description of problem:
When debugging satellite 6, foreman-debug is useful but has a limit that needs to be manually overriden of selecting the number of lines to capture, maximum. There is no option to capture all the lines generated since a day X which would be extremely useful in situations where the satellite was overloaded and we need to cpature logs of the action that originated the overload. The customer in case 01335769 generated the foreman-debug but it did not capture nearly enough logs because of all the errors generated while the satellite was overloaded. This feature would be extremely useful to technical support.

Version-Release number of selected component (if applicable):
6.0.6

Additional info:
this is opened by technical support, no customer has made this request.
