A new config object `encrypted` can be defined at any level and contain encrypted configuration strings. Initial use is for encrypting an npm token for use with the hosted renovate app.
Closes#650
Renovate config can now support the fields `npmToken`, `npmrc` and `yarnrc`. `npmrc` and `yarnrc` (note no `.` prefix) can be used as an alternative to checking the respective files into the repo and have the same effect. `npmToken` is a shorter alternative and allows for just the npm token to be added, defaulting to the public npm registry.
This is a major refactor of branch code to prepare for Yarn workspaces plus creating PRs for branches with failing lockfiles. Marked as "feature" to cause a minor version bump due to the moderate chance of accidentally breaking something.
Repository initialisation is refactored so that all package files and their content is retrieved up-front before an renovating begins. This allows us to know both how many package files as well as determine if there is renovate json in a package.json before triggering the onboarding PR.
Closes#634
This removes the need to JSON.stringify() objects in logs. Default bunyan fields plus our custom meta fields are stripped out, and everything else is stringified in the details field.
Closes#498
