[Feature request] Add Webhook management

[tasonface]

It would be cool to be able to add a webhook by setting method/url/params/body/headers and on response to access some nodes by eval-ing them and be able to use them in the next timer configuration or condition.

A basic example:

WEBHOOK:
GET https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd
Response is: {"bitcoin":{"usd":65960}}

Loop

1. WEBHOOK -> SPEAK "response.bitcoin.usd"
2. Timer 5 minutes

Another conditional use case for price alerts:

Loop

1. WEBHOOK -> SPEAK "WE DID IT!" -> WHEN "response.bitcoin.usd" >= 100000
2. Timer 5 minutes

It doesn't sound very easy. Do you have some suggestions on how to achieve or use it?
