[Fix] add post_install-hook-free LibComponentLogging specs and prepare for lcl_configure

Merge specs from https://github.com/aharren/LibComponentLogging-CocoaPods-Specs to fix LibComponentLogging specs which got broken due to the removal of the post_install hook.
See https://github.com/aharren/LibComponentLogging-Core/issues/24
Spec tests: https://github.com/aharren/LibComponentLogging-CocoaPods-Specs/tree/master/test

The LibComponentLogging specs require configuration files which must be present in the root folder of the project. These files can either be created manually or by using `lcl_configure`. The specs create `pod.lcl_configure` files which are picked up and processed by `lcl_configure pod`.
See https://github.com/aharren/LibComponentLogging-configure for details about `lcl_configure`.

The `LibComponentLogging-pods` spec contains `lcl_configure`, so it can be called via

    Pods/LibComponentLogging-pods/configure/lcl_configure pod

after a

    pod install/update
