* run unit tests in random order
running in random order highlights some interference between tests (mostly logging being enabled), and is a requirement for
mutation testing (ie, all tests must pass when executed in a random order).
* adding infection mutation testing
this adds the ability to run infection. It generates a lot of output, which is an exercise for another PR...
* replace assertwell/phpunit-global-state
the package was not compatible with phpunit 11. create out own test Trait, which handles
env vars, as well as general cleanup of the usual suspects of state that our tests mess up
* remove redundant tearDown functions
there's an after annotation on the trait to handle this
* use rector to upgrade tests for phpunit 11
* fixing CoversFunction for namespaced functions
* use FQNs in test attributes
* Cleanup `AttributesInterface`
- remove not required methods
- rename `::hasAttribute()` to `::has()` for consistency with `::get()`
* Remove public usage of `new Attributes()`
* Split `Attributes` into immutable attributes and mutable builder
* Remove `AttributesLimits`
* Remove `::incrementDroppedAttributesCount()` for now
Mainly useful for metrics sdk that has to rebuild filtered attributes.
* Remove obsolete cloning of attributes
* Update covers annotation
* Revert optional changes that might be controversial
allow logging methods in LogsMessagesTrait to be called from within either a static or non-static method.
in passing, adding a missing coversNothing annotation on a complaining integration test
