CircleCI Orbs

[frantjc]

forge shape circleci/node@5.1.0/install would be cool. Thoughts from first iteration:

main issue here is the lack of clarity on what directory should do what.

for concourse resources the working directory is the only thing that the resource is supposed to interact with

for github actions its GITHUB_WORKSPACE (working dir) RUNNER_TEMP and RUNNER_TOOLCACHE which all have relatively clear mappings

for these its...the whole file system. there's no "standard" where Orbs install tools, etc.

so its pretty unclear how the CLI should expose them, if at all
