New Rule: no-promise-chains-in-tasks

[Turbo87]

This rule forbids the use of .then(), .catch() and .finally() in task functions

Bad

submitTask: task(function*() {
  yield this.post.save().then(() => {
    this.set('saved', true);
  });
});

Good

submitTask: task(function*() {
  yield this.post.save();
  this.set('saved', true);
});

but then again something like let foo = yield import('foo').then(module => module.default) is probably legitimate 🤔
