Sort operations for a service in TraceSearchForm

[metalmatze]

Description
The TraceSearchForm currently shows all Operations as an unsorted list.
It would be really helpful if that list was sorted by name (ascending?)

I believe that this line has to have an additionally sort of the elements being passed?!
TraceSearchForm.js#L106

Steps to reproduce the issue:

1. Open the UI.
2. Pick a service.
3. Try finding a operation.

Describe the results you received:

Describe the results you expected:

I expect the dropdown to be ordered by name in an ascending order to more easily find the operation I'm looking for.

Additional information you deem important (e.g. issue happens only occasionally):

Additional environment details (Browser, etc.):

Chrome, but probably every browser.

I checked one of our services that has the most endpoints, they all came up sorted, but maybe it's a side effect of the storage backend returning them in that order.
