Formatting of data within status tab of devices

[BMH64]

Issue type: Bug

Properly format data under "status" tab within a device integrated with napalm

Python version: 3
NetBox version: 2.1.3

Currently under device status when integrating with napalm the uptime is show as a large number which I'm assuming to be seconds. Should be human readable such as YEARS:MONTHS:WEEKS:DAYS:etc;
Also the memory is formatted incorrectly shows as

Available	28445500MB
Used	10729512MB

We can probably do something with the uptime. It looks like your device is reporting memory in KB rather than MB. I'm not sure whether NAPALM's get_environment() takes a stance on unit.

I'm just going to omit the memory unit for now since it seems to differ by platform.
