Wait for cloud-init to complete before trying to run 'apt' commands

Description

We ran into some race conditions where `cloud-init` was changing `/etc/apt/sources.list` after or while the `apt-get update` command was run from the python role. This caused `python-minimal` to not be found on the next command, `apt-get install python-minimal`.

This PR adds a call to `cloud-init wait` before the `apt-get update` step to make sure `cloud-init` completes before we attempt installing packages.

Configuration Pull Request

Make sure that the following steps are done before merging:

  • [ ] A DevOps team member has approved the PR if it is code shared across multiple services and you don't own all of the services.

  • [ ] Are you adding any new default values that need to be overridden when this change goes live? If so:

  • [ ] Update the appropriate internal repo (be sure to update for all our environments)

  • [ ] If you are updating a secure value rather than an internal one, file a DEVOPS ticket with details.

  • [ ] Add an entry to the CHANGELOG.

  • [ ] If you are making a complicated change, have you performed the proper testing specified on the [Ops Ansible Testing Checklist](https://openedx.atlassian.net/wiki/display/EdxOps/Ops+Ansible+Testing+Checklist)? Adding a new variable does not require the full list (although testing on a sandbox is a great idea to ensure it links with your downstream code changes).

  • [ ] Think about how this change will affect Open edX operators. Have you updated the wiki page for the next Open edX release?
