DOC: config: Be more explicit in "allow" actions description

TCP/HTTP allow actions stop rules evaluation of the current section
only. Only the http-response description was accurate on this
point. Thus, the documentation is now explicit on this point for all
other concerned rulesets.

This patch may be backported, to all supported versions for tcp-request
and http-request documentation, and as far as 2.2 for http-after-response
documentation.
