[Server] Allow overriding the default file name pattern for Discovery (#292)

Browse source 
* Add optional namePatterns capability to discovery so that the default scan for `*.php` files can be overridden.

* add default to namePatterns docs

* add an error check if we manage to pass in an empty list of patterns

* add unit tests (and a static entry to classmap for composer.json so it autoloads from a non .php file for the test)

* run php-cs-fixer

* change how default namePatterns are set and make sure all the annotations are correct

* Fix bad whitespace

Co-authored-by: Christopher Hertel <mail@christopher-hertel.de>

* switch to a const default instead of nullable with a check in the function to convert null to a default

* make sure we handle empty arrays

* formatting fixes

* Apply suggestion from @chr-hertel

Co-authored-by: Christopher Hertel <mail@christopher-hertel.de>

* Add changelog entry
