Tracking URL

#954

• Extends setCustomPrebidServer method with nonTrackingURL parameter.
• Returns the PBS URL based on ATT status.

This will disrupt the existing integrations. I propose to add a separate method with an extra nonTrackingURL parameter.

I propose to implement this change on top of changes for #1006

The idea is the following:

• Deprecate constants and provide a new initializeSDK method which will accept the host URL as a parameter (both platforms)
• Introduce additional initialize SDK method with nonTrackingURL parameter.

After that, we will have a simple and clear initializtion interface.

The word Custom should be excluded from the initializtion interface since publisher will have to set the URL for any server without favorites.

If you think it make sense, please revisit the PR and make sure that we not only deprecate the usage of old constants but also provide an alternative initialization method where publishers will have to set the server URL directly. Also make sure that current initialization methods are marked as depricated.

@mdanylov-sigma, since the #833 is merged, please rebase the branch and finalize changes according to the previous comment.
