Disable only Pendo usage statistics

In our current brXM, there is a property "send.usage.statistics.to.hippo", which when set to false, does not send any usage statistics data. But, this property disables the legacy collection/sending of usage events and also the Pendo events with the navapp library.

For the needs of the test automation, it is better to have a specific property which disables only Pendo, while the legacy usage statistics events still work. This will help us continue testing the legacy usage events until they are replaced with Pendo.

And, we want to disable Pendo not to block the execution of the automated tests.
