[lnst] Introducing 'desc' command attribute.

[Jan Tluka]

This attribute can be used to pass a brief description of what command will do.
For example:

  <command type="test" value="Icmp6Ping" desc="ping6 to
loopback address">

If a command has 'desc' attribute defined it's value will be written to
info log.
