[BC-Break] Add request and response object to the preHandle and postHandle hooks

[acasademont]

I think it's reasonable to be able to access the request and response in the preHandle and postHandle hooks.

For example, I'm trying to trace some stuff using Blackfire.io and those hooks are the earliest possible place where I can start the probes. But I don't want to probe every request, only those that have a specific header, that's what I can't do right now. My only choice right now is starting the probe inside the app, in a Symfony request listener, but that's a bit too late if I want to profile the whole thing.

Would it make sense to (re)use one of the PSR-15 interfaces for this?

Tentatively tagged for 2.0 due to the bc break.

[acasademont]

We could definitely use the Middleware's interface from PSR15 but that would require quite a big rework (maybe in addition to php-pm/php-pm#439). This is not urgent at all, I already implemented what I wanted at the symfony event listener level instead of PHP-PM.

ping @acasademont I've started merging for 2.0. Is this something you'd like to have included? If its useful I feel it would be nice to build it on top of php-pm/php-pm#439, but keep all work in the slaves, not the master (even if that might not address all use cases).

[acasademont]

Yes definitely, all work should be kept at the slave level. TBH i'm not really sure about this PR anymore. It think is nice to have it for the sake of completeness but I can live without it.

Then lets put this on hold for time being.
