Feature request: global `credhub-namespace` flag

[joshzarrabi]

The credhub cli should respect a credhub-namespace global flag and environment variable which is a credhub path that will prepend all variables that the credhub cli consumes.

All concourse variables must start with the path /concourse/main/ and while manipulating them with the credhub cli I often forgot to add this path at the beginning and end up with credentials stored at the wrong path.

What did you expect to happen?

I would like to set an environment variable CREDHUB_NAMESPACE which specifies the starting path of all credhub variables set in my environment.

For example:

$ export CREDHUB_NAMESPACE=/concourse/main
$ credhub set --name some_concourse_var --type value --value some-concourse-secret
id: some-id
name: /concourse/main/some_concourse_var
type: value
value: <redacted>
version_created_at: "2019-07-23T15:47:19Z"

If you have interest in this/another use case, please comment on this so that we can gather if there's interest in this feature.

We think creating an environment variable would create unnecessary confusion. Abstracting the namespace might create more overhead in this case rather than simplifying the problem.
