A separate routine is run after branch creation to detect any branches that should be deleted. A branch will be removed if:
- It was not created by renovate in the last run, AND
- It has no PR, or its corresponding PR is not mergeable
Closes#426, Closes#428
This starts off [#359](https://github.com/singapore/renovate/issues/359) (configurable status checks) but only implements one sub-feature of it: disabling status checks to allow automerge if tests fail or if no tests are present.
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.
