[rancid] New Force10 f10rancid.in for FTOS devices

[Greg Hankins]

A new f10rancid module that supports all Force10 devices running FTOS is
now available. John Heasley did most of the work, and I added some tweaks
for specific devices.

I tested this version on the E-Series, C-Series and S-Series running
FTOS 7.5.1 and 7.6.1 but it should work fine on older FTOS versions too.
Devices running SFTOS are not supported.

It will be included in an upcoming release but in the meantime you can
grab it here: http://www.twoguys.org/~gregh/software/f10rancid.in .
Then move it to the bin directory.
