Continues Delivery Strategy

Stage 1
https://github.com/decentraland/catalyst/issues/1036

Stage 2
- Create a configurable auto-update setting for patches: meaning that there should be an environment variable in the [Catalyst Owner ](https://github.com/decentraland/catalyst-owner) project to set opt-in/opt-out of the auto-updates. When opt-in, a Catalyst should be listening for new patch versions and in the case that there is one, it should run the ./init.sh to get updated. This process should only be for patches and not for minor or major, in some of those cases a controlled rollout is needed and having an auto-update could cause all the services to be down making the access to Decentraland impossible
