Issues-2516 - Resolved IBM Cloud integration issue

[codyreinold]

Description

This is a rewrite of the IBM Cloud Text to Speech connector. Resolves #2516. Previously, we were using the speech_recognition package to interface with IBM Cloud. However, recently IBM moved from user / pass-based auth to api key-based auth. This fix moves all functionality for IBM Cloud into the mycroft-core codebase (using the requests package).

How to test

Create an IBM Cloud account, if you do not already have one. Enable "Speech to Text" to receive an API Key and URL. Setup Mycroft config file according to documented format (see codebase).

Once configured, start Mycroft in debug mode. Test different scenarios (wakeword + phrase, wakeword + silence) to ensure acceptance of functionality. Error message on silence is specific to this integration, so can be used to validate IBM plugin is being used. Usage can also be confirmed in IBM Cloud usage dashboard (https://cloud.ibm.com/billing/usage) and digging into the service usage report.

Unit test covers basic functionality (generation of request) and mocks the response. Additional tests could be added to test malformed responses, but I wanted to adhere to current test pattern.

I think it looks very good and can be merged as soon as the CLA process is completed.

I do wonder why params are explicitly added to the url instead of using the requests.post() params argument?
