Finding correct tenant is difficult in Traffic Portal

[shamrickus]

This Improvement request (usability, performance, tech debt, etc.) affects these Traffic Control components:

• Traffic Portal

Current behavior:

With a CDN at scale with many Tenants, any dropdown Tenant selection box has so many options that it makes it quite difficult to find the appropriate option. All children under a tenant are sorted, but that is not sufficient when dealing with nested tenancy. This issue is exasterbated by the face that child tenants are prepended with -- making the default search functionality most browsers offer unusable (open dropdown, type letter, it goes to first option with that letter).

New behavior:

Filtering the drop down or having some way to find a specific tenant would be great.

Not sure how hard it would be/if AngularJS Material has been updated in the past 6 years since I last used it, but like I said on this other comment on #2908 it could be implemented as an Angular Material "Tree".
