Log function

[jf-uu]

Is your feature request related to a problem?
When printing out custom messages from pipelines and commands, they don't match DevSpace's output style.

Which solution do you suggest?
A new log function exposed by DevSpace which takes level and message parameters:

log info "Hello, world!"

The message output should match the devspace output format (i.e. colored level followed by message).

Which alternative solutions exist?
echo
