* Update docs to use kubectl long flags
* adding back in the --filename flag (lost when manually merged)
* notice a few missed
* notice a few missed '-f' flags
* change -o to --output
* source-to-url-go: support multi-line base64 output
if my password is long "echo password | base64" will yield in a multiline
string that can confuse users about how to put that thing in Kubernetes
Secret manifest.
Adding -w0 (and for macOS/BSD base64(1), -b0) solves that problem.
