Openwhisk: Add a command to return the version of the CLI

[cfjedimaster]

There is no available command to wsk that returns the version of the CLI installed.

[rabbah]

Try: wsk property get -h

[cfjedimaster]

Confirmed this works: wsk property get --cliversion

However, this should be exposed on the top level help screen. It is a pretty common feature (imo) should be made more evident.

[rabbah]

Sure wsk --version makes sense as an alias.

Looks like there is two different converstations going on here. One about the wsk CLI and the other about wskdeploy.

[rabbah]

This issue should address wsk not wsk deploy.

[lzbj]

@rabbah, is this one we need fix or not?

[rabbah]

We should add wsk --version and it would be great to also add an auto update feature as well or at least notify the user there is a newer version.

[markusthoemmes]

We'll need to improve our build processes to not create a new CLI version if no code has changes, as the CLI is currently versioned by date and you don't want to notify users everytime a new OpenWhisk is deployed.

[rabbah]

Agree - the date was more intended to show the build date, not the actual version. We could adopt semantic versioning and do it manually to get going.

[lzbj]

manually you mean we pass in build number as arguments everytime we updated code?

[dubee]

A new CLI is not created if the code has not been changed as long as there is already a Docker container of the built CLI in the cache.

[lzbj]

Ok, got it.
