CI

Added CI:

• node_modules
• lint

lint job is eslint with prettier. Currently checking only libs folder.

Added npm scripts:

• lint for checking errors
• lint:fix for fixing errors that eslint is able to fix and auto-format with prettier.

Right now allowed lint to fail (allow_failure: true) as code contains too many errors.

TODO:

• @moeiscool verifies that Coding style is ok, by running npm run lint:fix and checking files in libs folder
• if @moeiscool is satisfied by Coding style generated by eslint and prettier, then he will run npm run lint:fix and commit lib folder changes before merge
  • to avoid merge conflicts, this branch should be rebased to latest dev branch (@petslane can rebase on request)

Additional change not related to CI

backblaze-b2 module starting from 1.1 requires node 10, so updated dependency to require backblaze-b2 version up to 1.0 and set shinobi node requirement to version 8.
