"yarp wait" should have an option to wait for the nameserver

At the moment, in order to wait for the yarp nameserver, you have to run

yarp wait /root

which means you have to know the name of the nameserver, and is not very convenient for scripts that should run on different robots. As described in #2423, adding a scriptable option to yarp namespace could be useful.

Anyway I believe it would be just easier to have a yarp wait --namespace option or something similar to wait for the yarp nameserver to be available.
