* fix(deps): update dependency get-installed-path to v4.0.3

* fix

It appears that writing the existing lockfile before regenerating a new one can help speed some resolutions up.

Closes #815

fixes a few incorrect/outdated commands.

- Add link to config-help
- Update description/benefits

Setting lockFileMaintenance.groupName =  null will prevent the case where the user configures a repository groupName like “all” and then that group inherits the schedule of lock file maintenance. Instead, there will be renovate/all and renovate/lock-file-maintenance.

Fixes #885

* fix: info message if automerge branch fails

* fix snapshot

* use keyv for cache

* set expiry to 5 minutes

Closes #267

yarn v1.1.0 has a bug with version resolutions, so rolling back to v1.0.2 until a fix is available. See https://github.com/yarnpkg/yarn/issues/4600 for details

* chore(deps): update dependency prettier to v1.7.3

* update lockfile

Closes #843

Having eslint flag prettier "errors" in editors can be rather painful. Also chose against linting staged files for prettier because I like to stage partials. Instead:
- Recommended to use plugins for editors to format on save, e.g. `prettier-atom`
- Prettier will be run as part of `npm test`

* fix: write npmrc to subdirectories with lock file

* fix lint

Fixes #849

This feature adds support for ignoring .npmrc files in a repository. Set config option to true if you wish to ignore.

Closes #851

Previously, Renovate assumed that any yarn workspaces configuration would be in the root of the repository. Now, workspaces can be located within a subdirectory, e.g. `frontend/`. Note: Renovate still supports only one workspace per repository, please file an issue if you require more than one.
