Install getting started

fix #969

[jumaffre]

As I understand it, the expected workflow is:

1. Download the CCF install on your local machine (e.g. laptop). Untar.
2. Install Azure CLI.
3. Run the scripts in getting_started/create_vm to create a new DC VM.
4. SSH onto the VM and download the CCF install again. Untar.
5. Run the ansible scripts in getting_started/setup_vm
   (Alternative to 5. is to run the ansible playbooks directly from the machine on which 1. was run, provided that ansible is installed there).
6. Build you app.

All files apart from getting_started/create_vm in the first install are not actually required but I guess it's the best way to distribute this script. An alternative would be to package getting_started/create_vm and export it as a release artifact. What do you think?

2. is done by ./pre_make_vm.sh, so it's sort part of 3.?
3. well yeah...

I think I prefer to keep things simple for now with a single SDK tarball that has All You Need (tm), but arguably the create_vm stuff could migrate elsewhere, since it's not actually CCF-specific (oe_engine? openenclave-azure-get-started?) and we could just reference it.

I suspect this is a post-0.9 thing though.
