Web hook setting

Hi all,

I am setting trigger using web hook to send a message to Azure Message Bus.
I have set some extra headers like Authorization but seem to be the plugin does not use those headers when execute web hook

Anything to fix that

After modifying alert plugin, I saw that the plugin had sent extra header also. the root cause here is, ES node had not yet added to Azure Message Bus white list

Good to know that header has been sent.
