[c-nsp] enable secret 'password'

[Andrew Miehs]

Hi all,

Cisco Cat 4500 running cat4500e-universalk9.SPA.03.03.02.SG.151-1.SG2.bin

 Warning: The CLI will be deprecated soon
 'enable secret 5 $xxxxxxxxxxxxxxxxxxxxxxxxx/'
 Please move to 'enable secret <password>' CLI

Any suggestions on how to get around this - I don't really want the
password lying around in plain text...

Andrew
