* Add support for unix socket as upstream
* Add CHANGELOG.md entry
* Add Unix socket documentation
* Don't export unixRoundTripper, switch from string prefix to Scheme match
* Add basic unix server mock
* Add some tests and comments
* Fix uninitialized user claim
Some providers doesn't initialize data with setProviderDefaults function
(keycloak-oidc for example), therefore UserClaim is never initialized
with the default value and stay as an empty string.
This result in an empty user.
* Add CHANGELOG.md entry for #1873
* Call setProviderDefaults where missing
