feat: no column header when running `metal capacity get` without any [--options]

[waltribeiro]

What problem are you facing?

The first table header is empty when running metal capacity get without any [--options].

However, including an option will return all column headers, for examplemetal capacity get -m sv.

Thoughts

So the first column has no context that ml1 or ld7 refer to the data centers. And if we put a header there, then I suggest "DC" rather than "METRO" (because a 'DC' header works whether it's a metro or a facility).

Steps To Recreate

1. Deploy a server on console.equinix.com
2. Run command metal capacity get (the first column header will be empty)
3. Run command metal capacity get -m sv (all column headers will be populated)

How could the Equinix Metal CLI help solve this problem?

Perhaps leaving it empty was intended because LocationField in Line 92 refers to both Metros and Facilities, so as to avoid a metros/facilities header conflict in that first column (?).

Notes

I confirmed that all other get commands have table headers, some examples from Docs:

metal device get
metal event get
metal gateway get
metal hardware-reservation get

So metal capacity get seems to be the only column header that returns empty.

Note

I submitted this as a feature instead of a bug because the empty header is not breaking anything.
