Add deployment endpoint test UI with optional drag and drop image payload.
It's essential to verify that your deployed endpoint works as excepted before rolling it to production,
previously testing was done through the command-line but now you can just use the Valohai web app.
We'll bring more automation to check endpoint "health" in the future.
Internal crash reporting now includes user contact information.
Valohai support team can now reach out back to you automatically.
