Closes #427

This changes how group are configured to align with the new lock file configuration.

BREAKING CHANGE: old group* template options are no longer supported but can be migrated into group object

This feature now allows a custom schedule to be defined for lock file maintenance. It is now enabled by default but runs only before 5m on Sundays. Closes #399

BREAKING CHANGE: lock file maintenance is enabled by default.
Rules will apply to both yarn and npm (npm is yet to be implemented however). Existing mainainYarn* variables are removed and replaced by new lockFileMaintenance object.

This PR adds a scheduling feature, including timezone support.
It's described in detail in the FAQ, but the summary is:

*   Timezones can be defined so that schedules are written in timezone of target repository
*   Schedules can be written in "plain english"
*   Multiple schedules allowed
*   Schedules can be defined all the way down to package level
