Add a field for height

[mrtn-r]

NetBox version

v3.7.4

Feature type

Data model extension

Proposed functionality

Add a field for "height" in the "Location"-section of the device under "longitude", together with a "units" field.

The "height" field should accept any positive or negative numeric value, while the "units" field should accept anything. Examples (height; units):

• "1.5; Level" Height could be a level in a building
• "-5; m NAP" Physical height with accompanying vertical reference [^1]

[^1]:There are multiple vertical reference points, depending on the country you're in, see for example https://en.wikipedia.org/wiki/Vertical_datum#/media/File:Vertical_references_in_Europe.svg

Use case

When having multi-story buildings, latitude and longitude are just not enough to locate a device on a map.

Database changes

Two new fields are required
