Introduce Payload Inspector for SiPixel conditions

[mmusich]

PR description:

This PR aims to introduce the first few classes for the inspection of SiPixel conditions, namely the SiPixelLorentzAngle and the SiPixelQuality. More classes for other conditions types will be added at a later time.

PR validation:

The code has been privately tested using the scripts provided in the CondCore/SiPixelPlugins/test directory.
In the particular case of the SiPixelQuality Bad ROC maps a dedicated validation has been done, by cross-checking the output of the payload inspector, with the content of the MonitorElements used for monitoring the PCL output in the Phase-1 pixel DQM ( example )
Example of output image to be displayed in Conditions Browser from one of the classes introduced here:

@mmusich this PR is not supposed to affect production workflows, but it provides standalone tools to inspect payloads, am I correct?

that's right. It needs to be in release in order for the ConDB Browser to be able to access to the plugin libraries.
