[PHP] By default should use static Configuration class instance

[DarkSide666]

For PHP.

By default should use static Configuration class instance, otherwise new instance is created every time you make an API call.

Before this PR every time you create new API object and do not pass Configuration object as 2nd argument to API class constructor it creates new Configuration instance. This is wrong, because Configuration class is meant to be Singleton - so Configuration::getDefaultConfiguration() should be used instead.

@wing328 could you please do this for me?
I'm on Windows and was trying to run generate_samples script from windows linux console (WSL), but still no luck.
It throws Error: Unable to access jarfile /mnt/c/wamp/www/DarkSide666/openapi-generator/modules/openapi-generator-cli/target/openapi-generator-cli.jar I guess this is not gonna work on Windows :(
Maybe I can just merge latest commits from your master branch into my PR and then it should be ok, isn't it?

I'm OK with this change, using static methods and properties is a code smell in 99% of the cases, but here the assumption is you should get the (supposedly pre-configured) default config instead of just an empty config object.

Not because of performance but because of the behavior, the solution is still the same. 👍

Yes exactly. Normally because Configuration is static object, then it's meant to be pre-configured and then can be automatically be reused in all API calls done later in code.
But now you have to always do like this to use this "global" Configuration in your API classes:

$api = new \Example\Client\Api\PaymentsApi(
    null, // uses default \GuzzleHttp\Client()
    \Example\Client\Configuration::getDefaultConfiguration()
);
