Use StructArmed on QA

[samsonasik]

This PR adds StructArmed to QA:

https://github.com/boundwize/structarmed

It is a configurable PHP architecture guards with built in presets (psr4, mvc, and so on). This PR apply StructArmed with register:

• PSR4 Preset
  This PR start apply StructArmed with initialize using PSR4 preset, and already help fix 8 violations.

• I also enable ruleset so it show more ability of layering setup to define which layers each layer is allowed to depend on.

• Register to Github workflow.

Hey @samsonasik, just FYI, I didn't ignore your patches about this (and on other repositories as well), but I simply didn't get to play around with the tool yet.

@kukulich @asgrim do you have opinions on a layer structure we could follow for this project, BTW?

[samsonasik]

@Ocramius that's fine, if ruleset layering need in separate PR and just need apply PSR4 for starter, just let me know ;)

I'm not against new check tool however the configuration looks too complicated to me: https://github.com/Roave/BetterReflection/pull/1580/changes#diff-6c750795fe8e9ac3fc3936402fef25d2ca69ca1d01ef0f16c2ad8b27cde4b041

@kukulich sure, I've updated the config to use layer() over layerPattern() when possible to simplify the config 👍 09704bd

Less regex and should be ok now 👍 Just let me know if you need another simplification even more.

[samsonasik]

@kukulich I've cleaned even more so no more regex in the config 6b07a11 👍

It clean now, no more complicated config 👍

Just let me know if you doesn't want to ruleset() definition and just the PSR4 preset for this starter PR :)
