Further Improvements to password masking in powerconnect.rb from #1212

[clifcox]

In both the 3400 and 6200 series the previous regex would miss the following passwords:

password 123456789abcdef0123456789abcdef0 encrypted
enable password 123456789abcdef0123456789abcdef0 encrypted

This update changes the output From:

username "root" password <hidden> level 15 encrypted
username "foo" password <hidden> level 1 encrypted
line telnet
password 123456789abcdef0123456789abcdef0 encrypted
exit
[...]
enable password 123456789abcdef0123456789abcdef0 encrypted

To:

username "root" password <hidden> level 15 encrypted
username "foo" password <hidden> level 1 encrypted
line telnet
password <hidden> encrypted
exit
[...]
enable password <hidden> encrypted

It is a bit odd that Dell would choose to insert "level ##" in between password, and <secret>, but here is an example from a 3448: enable password level 15 123456789abcdef0123456789abcdef0 encrypted
