After envoyproxy#11670, the CSRF filter started failing for us. This change fixes 3 issues that were uncovered after moving to gURL for parsing URLs: 1) the hostAndPort() utility method, in the CSRF filter, was returning a string view of a stack variable. 2) the Origin header always includes the scheme, so let's ensure this is illustrated in tests (which were missing this and passing due to relaxed checks). 3) the Url::initialize method expects an absolute URL, something that the CSRF filter wasn't complying with.

Two things were missing: * the origin/referer headers in the integration test needed their respective schemes. * for some reason, headers.Scheme() is nullptr during integration tests... Hmm, not sure why. Signed-off-by: Raul Gutierrez Segales <rgs@pinterest.com>

Commit Message: csrf: fix issues with host/origin header parsing
Additional Description:
After #11670, the CSRF filter started failing for us.
This change fixes 3 issues that were uncovered after moving
to gURL for parsing URLs:
the hostAndPort() utility method, in the CSRF filter, was
returning a string view of a stack variable.
the Origin header always includes the scheme, so let's ensure
this is exercised in tests (which were missing this and passing
due to relaxed checks).
the Url::initialize method expects an absolute URL, something that
the CSRF filter wasn't complying with when parsing the Host header.
Risk Level: low
Testing: changed/added
