Add support for git credential pass-through to studio.

[rhass]

As a developer, I would like to be able to access private repositories which require some form of authentication to clone and for security reasons I do not want to store the credentials within the plan itself.

See the following thread discussion on slack (hopefully it doesn't vanish into the ether): https://habitat-sh.slack.com/archives/C0VBY57UP/p1492113443402203

There is this feature that was added way back to support sourcing of .studiorc files if it exists. When you enter the studio, Hab would automatically source it. You could potentially place any git creds like tokens and/or any other secrets that need to get passed.

The primary development scenario that we are working towards is to have the developer clone their software onto their host machine and then enter a studio from there. With that said, pulling from git from within the studio is something that you may still need to do given this scenario. For example, you may have a build tool which pulls a dependency from a private git repo which requires these credentials as part of the build process itself.

I'm going to mark this as help wanted for now. I think @bdangit is on the right track with the .studiorc file. If this works well we should promote this in the docs and ensure there's a global .studiorc which would prevent you from needing to create one for each software project to get common credentials such as these into your studios.

I am going to close this as I .studiorc does what we need.

Copying this from the other issue:

...in my opinion the experience (using .studiorc for this functionality) falls short of hab's standards. The way it's done now is referenced in this documentation issue: #3145 but it seems silly for everyone to need to cargo-cult that code around.

If at all possible, authentication should just follow me in to the studio so I don't think about it. If some extra configuration is actually required (maybe my SSH key has a non-standard name or whatever), it would be nice if I got an error message that helped me figure out what to do. It's tricky since the build tool is in charge but maybe some magic could be done by wrapping git clone and annotating the error message in some way.

Can anybody help me to pass host ssh key to studio (like while doing hab studio enter) so that can be accessed at build time.

Maybe the new secret sharing feature of studio can help? (can't find doc though)
