[MOD-2109] Omniture: Improve module documentation

Issue

The current documentation of the module will require more specific information related to the usage of the methods, as some of them don't indicate the required parameters and cause error for the customers.

Example

createMediaSettings: This parameters are mandatory, but there is no mention of it in the docs * name * length * playerName * playerID collectLifecycleData: The documentation says that the parameters are optional, in iOS works but when trying to call it in Android customer receive this:

[ERROR] : V8Exception: Exception occurred at cbclib/util/Analytics.js:1: Uncaught Error: collectLifecycleData: Invalid number of arguments. Expected 1 but got 0
