[FEATURE] Add a filter bar in INDICES screen

[fbaligand]

Is your feature request related to a problem? Please describe.
When we go to "INDICES" screen, we can see all indices list, but we can't filter indices list with some keyword.
This is especially annoying when you have numerous indices

Describe the solution you'd like
On "INDICES" screen, add a filter bar, where each time we write a string (say "my-index"), the indices list is refreshed with only indices containing the typed string (say "my-index").
Ideally, filtering is done "as you type" in the filter bar.
Finally, it would be great to also have "filtering as you type" in "Connect" view, in the combobox to select an index.
