v2: Updated for 2019

Breaking Changes:
 * CrudService: all callback functions return promises. Callbacks are optional.
 * `CrudService._find` no longer returns a query. use CrudService._buildQuery instead.
 * `CrudService._createWithRetry` signature has changed (is no longer recursive)
 * `CrudService._update` no longer returns the isModified flag
 * `CrudService._delete` no longer returns the isModified flag

Additional Changes:
 * Updated dependencies to latest versions (Mongoose 4 -> 5)
 * Removed Yarn
 * Updated eslint config
 * Updated travis testing environments
 * Updated package release files
 * `Mongoose.set('useCreateIndex', true);` is done automatically
 * Mongo `useNewUrlParser: true` is done automatically
