Add Test Connection Button to UI

[bbovenzi]

Description

Airflow 2.x had the ability to test a connection from the UI, which was controlled by a config flag. We have the rest api endpoint but not the UI button. We should re-add the mising Test Connection button but only enable it if the test_connection flag is also enabled.

Hi @kevinhongzl , hope you are well any estimated timeline on when this issue might be resolved ?

[bbovenzi]

@oceands This is an open source project. The vast majority of people who contribute to it do so in their free time. So please be patient, especially since this wouldn't come out until we release Airflow 3.1 which won't come out for a few months.

@bbovenzi Thank you for your kind words. Guess I found the reason why we have such a supportive and prosperous community here for airflow developers :) I had a lot on my plate this week, so I plan to submit my PRs by next Wednesday (or probably earlier because I've started working on it).

@oceands It's great to hear someone looking forward to this feature! You're welcome to review the work I've done once I send the PR!
