Output stdout from long running task

[citizen-stig]

Tested with following markdown:

This is how bashtestmd works.

You can start with long-running command

```sh,test-ci,bashtestmd:long-running,bashtestmd:wait-until=PING
$ ping 8.8.8.8

And then do couple other commands.

This will just check exit code

$ date

This will compare output

$ echo "Hello world"
Hello world

and if output does not match, it will fail, and also prints output of the long running command

$ whoami
super-root```

and output is:

Running: 'ping 8.8.8.8'

We should also bump the patch version number.
