Add client_secret to the list of forbidden headers

[javixeneize]

Description

Drheader can detect headers that leak sensitive information, as server, or X-Client-IP. We want to add another header, x-ibm-client-secret, to the list of headers not allowed

What I Did

The new header to be added to rules.yml should be:

X-Ibm-Client-Secret:
    Required: False
    Enforce: False
    Value:

[javixeneize]

Drheader only analyses the headers in the response, and this is in the request. Issue closed
