Added logout ability (argocd logout)

[simster7]

Implements #1210. Pretty self explanatory. Current behavior if logging out from a currently selected context is to automatically select the first context that is still logged in, not sure if this is the desired behavior.

Looks good, but could this have some tests please?

[simster7]

@alexec Added tests!

@alexmt or @jessesuen is this something you'd like to review? I don't know the code.

I took a quick look. This PR is actually implementing context deletion, which is actually different (but useful) request. argocd logout should leave the contexts in place, but simply delete token information. For context management, we can put this under the argocd ctx set of commands. For example, this work would probably make sense as:

argocd ctx --delete

Which will delete the current context.

@jessesuen I have now included an argocd context --delete flag that will delete the current context and have modified the argocd logout CONTEXT command to only delete the relevant auth-token and refresh-token. Sorry for the delay.

Also, the failing E2E test seems to be a flaky test related to GitLab authentication.

Conditional approval. Please update dependencies to remove changes to openapi_generated.go

[jessesuen]

Thanks for this

[jessesuen]

These openapi changes are unexpected. Can you run:

brew upgrade protobuf
brew upgrade go-swagger
make codegen

[simster7]

@jessesuen Ready!
