[v2.9.0.beta2] Fix precompiling assets by using new ember cli approach
Solves #1
This commit solves the precompiling assets operation that as of v2.9.0.beta1
upstream team started using ember-cli
.
Also, it parametrizes the worker_process using by nginx, according to https://github.com/discourse/discourse_docker/commit/65fa2054db98d4e9e8cfcadf2a30ca8a6a06b19f (although no impact on us for the time being).
