Uses of deprecated API can be used to cause DoS in user-facing endpoints
Discription

### Impact
Several `HandleRoute` endpoints make use of the deprecated `ioutil.ReadAll()`. `ioutil.ReadAll()` reads all the data into memory. As such, an attacker who sends a large request to the Argo Events server will be able to crash it and cause denial of service.

Eventsources susceptible to an out-of-memory denial-of-service attack:

– AWS SNS
– Bitbucket
– Bitbucket
– Gitlab
– Slack
– Storagegrid
– Webhook

### Patches
A patch for this vulnerability has been released in the following Argo Events version:

v1.7.1
