burn: Test cms burn raspberry with and without --ssid=

[jpfleischer]

We must test cms burn raspberry to burn a cluster and we must test the --ssid= parameter.

If we leave the flag with no ssid, as in --ssid=, then the program should probe the ssid that the computer is using.
We can even use --ssid=Find among other strings like T and t and 1 and so on.

If we enter an ssid such as --ssid=Netgear then the program should use the specified ssid and, if password is not specified, then the program will ask for a password.
If we do not specify --ssid at all then no SSID is used since we assume it is an ethernet setup.

Also, when prompting the user for a password, it should not be printed in plaintext.

correction to meaning

• --ssid=. or something than it probes, if we do not specify it assumes its on the network and we need no wifi
• --ssid=find does the same as .
• --ssid=SSID the ssid is specified from the commandline a find should still be performed and an Console warning should be issued alerting the user that the wifi was not found.
• --wifipassword or whatever finction allows to specify it on commandline. if it is ommitted and ssid need to be specified, than the wifi password need to be asked for. we use a new cloudmesh.getpass function that woks on all OSSES.important is that the password is not printed. must work in cmd, pwereshell, gitbasj, mac, linux
