Log messages are no longer being translated. This removes all use of the _LC, _LE, _LI and _LW translation markers to simplify logging and to avoid confusion with new contributions.

This is the single point of entry to generate the sample configuration
|
|
file for Masakari Monitors. It collects all the necessary info from the
|
|
other modules in this package. It is assumed that:
|
|
|
|
* every other module in this package has a 'list_opts' function which
|
|
return a dict where
|
|
* the keys are strings which are the group names
|
|
* the value of each key is a list of config options for that group
|
|
* the masakari.conf package doesn't have further packages with config options
|
|
* this module is only used in the context of sample file generation
