* Strip X-Forwarded auth headers from whitelisted paths
For any paths that match skip-auth-regex, strip normal
X-Forwarded headers that would be sent based on pass-user-headers
or pass-access-token settings. This prevents malicious injecting
of authentication headers through the skip-auth-regex paths in
cases where the regex might be misconfigured and too open.
Control this behavior with --skip-auth-strip-headers flag. This
flag is set to TRUE by default (this is secure by default, but
potentially breaks some legacy configurations).
Only x-Forwarded headers stripped, left the Authorization header
untouched.

When using the configured provider JWT Verifier, it makes
sense to use the provider `CreateSessionStateFromBearerToken`
method. For any extra JWT Issuers, they should use a generic
default verifier.
* Add an option to allow health checks based on User-Agent.
* Formatting fix
* Rename field and avoid unnecessary interface.
* Skip the redirect fix so it can be put into a different PR.
* Add CHANGELOG entry
* Adding a couple tests for the PingUserAgent option.
* Implements -real-client-ip-header option.
* The -real-client-ip-header determines what HTTP header is used for
determining the "real client IP" of the remote client.
* The -real-client-ip-header option supports the following headers:
X-Forwarded-For X-ProxyUser-IP and X-Real-IP (default).
* Introduces new realClientIPParser interface to allow for multiple
polymorphic classes to decide how to determine the real client IP.
* TODO: implement the more standard, but more complex `Forwarded` HTTP
header.
* Corrected order of expected/actual in test cases
* Improved error message in getRemoteIP
* Add tests for getRemoteIP and getClientString
* Add comment explaining splitting of header
* Update documentation on -real-client-ip-header w/o -reverse-proxy
* Add PR number in changelog.
* Fix typo repeated word: "it"

* Add -user-id-claim to support other claims than email
Fix#431 - This is a minimal change to allow the user to configure which claim is
the source of the "user ID".
- Add the option `user-id-claim` (defaults to email)
- OIDC extracts this claim into session.Email (to be renamed later)
- providers: add `CreateSessionStateFromBearerToken` with a default impl taken from
`GetJwtSession` and overridden by oidc to respect `user-id-claim`
Once #466 is merged, I can continue to rename SessionState.Email to .UserID
and add HTTP headers with a corresponding name.

* Review feedback: Don't extract claims manually
Instead, parse them twice - it might be sligtly slower but less bug-prone as the code evolves.

Previously in #401, an option was added to support forwarding the email
address as the username to the upstream service when the PassBasicAuth
option is used.
The PassBasicAuth option is not appropriate for all users, with PassUserHeaders
allowing very similar functionality without specifying a basic auth headers.
The PreferEmailToUser option has been expanded to support the PassUserHeaders
option.
* Add support for preferred username.
* Add missing TOC entries.
* Add note about preferred_username support.
* Adjust tests.
* Check on not implemented error for GetPreferredUsername() call.

With some providers the Username is an upstream Unique ID, like fex. in the
case of Google.
When matching this with downstream databases, it's sometimes preferred to use
the email address as the known identifier.
However, when _mixing_ this with sometimes other sources, like htaccess, which
doesn't have a concept of an email address, it can turn difficult.
This change makes the headers _prefer_ to use the Email address, if such exists,
for the Username identifier when passing data to downstream services.
Defaults to Off.

Values of 'lax' and 'strict' can improve and mitigate
some categories of cross-site traffic tampering.
Given that the nature of this proxy is often to proxy
private tools, this is useful to take advantage of.
