Subject: util.prosodyctl.shell: Allow passing a single command as argument

Test procedure:

$ prosodyctl shell 'server:version()'

Expect:

> OK: hg:926d53af9a7a

$ prosodyctl shell 'server:version()' 'hello'

Expect:

> Only one command is supported as argument

$ prosodyctl shell 'lorem ipsum'; echo $?

Expect:
> Sorry, I couldn't understand that... console:1: syntax error near 'show'
> 1 (error code)

Thanks Menel for mentioning the feature
