Note that this may change the origin of logging when classes
have been subclassed, as the logger origin will use the class
name that defined the logger where previously the subclass type
would be used. In scenarios where external libraries subclass
httpclient utilities this allows httpclient logging to maintain
the `org.apache.hc` prefix instead of inheriting arbitrary
subclass names.
Using some logging frameworks this may result in reduced churn
when httpclient components are created (new connections, for example)
because loggers are looked up once per class.
Throughout the code the terms 'authScheme' and 'scheme' have been used
synonymously for an AuthScheme instance and a string-based auth scheme
name. To avoid confusion, fields, methods and variable have been adapted
to distinguish both properly. If necessary, Javadoc has been modified to
denote the nature of the input.
Also an auth scheme name is retained as-is, but normalized to lowercase
if comparsion is required.
This closes#193
Modeled after StandardCharsets, the new class indicates a non-exhaustive
list of standard auth schemes by name supported by the HttpClient. The
previous enum suffered from two issues:
* it was exhaustive implying that no more auth schemes can be supported
* its sole purpose was to contain an id for the declared auth scheme;
the enum values theirselves were never used directly
This closes#196
