Formatting of cable length in cable trace

[candlerb]

Environment

• Python version: 3.5.2
• NetBox version: 2.5.12

Steps to Reproduce

This is a minor issue, but the display of cable length units could be improved.

1. Create cable with length 200, units Centimeters
2. Trace the cable

Expected Behavior

Length to be shown as "200cm" or "200 Centimeters"

Observed Behavior

This is ugly because "200" and "Centimeters" are pressed up against each other; also there is a leading hyphen which looks like a minus.

I would prefer displaying the abbreviated length unit here - e.g. cm, ft etc (*) - in which case having no space is entirely appropriate. Otherwise, insert a space.

Please also omit the hyphen unless there is a field to separate it from. (I guess this is for the cable label? But in this case, the cable is unlabelled)

(*) There's no need to have both long and short versions - I'd be entirely happy if the abbreviations were used everywhere.

CABLE_LENGTH_UNIT_CHOICES = (
    (LENGTH_UNIT_METER, 'm'),
    (LENGTH_UNIT_CENTIMETER, 'cm'),
    (LENGTH_UNIT_FOOT, 'ft'),
    (LENGTH_UNIT_INCH, 'in'),
)
RACK_DIMENSION_UNIT_CHOICES = (
    (LENGTH_UNIT_MILLIMETER, 'mm'),
    (LENGTH_UNIT_INCH, 'in'),
)

If you Label the Cable this would be visible on TOP of the trace View.

With Label:

Without Label:

I think this is a simple Bug because the one character is too much:

Just want to add that according to SI rules, there should always be a space between number and unit even if the unit is abbreviated. Source: SI Brochure, Section 5.3.3: https://www.bipm.org/en/publications/si-brochure/section5-3.html
