arista_eos_show_interfaces: Capture additional information

[Mikeg2881]

--Another one i cant take credit for as cursor made the fix and it appears to work--

Looking to make this textfsm a bit more robust. I matched the names from show int from cisco ios.

The current template skips the rate and error block after Last clearing of "show interface" counters. Those lines are present on Ethernet, Management, and Port-Channel, but they were unmatched/skip-only, so parsed output had no rates, packets, or errors.

Agreed, the template does not capture all of those fields currently.

There appears to be a small copy+paste indentation error above.

Regarding capture group normalization (make the names match), the closest comparisons are the NXOS sh int template and the XR sh int template.
