SDL 0282 - Alert Manager

[NicoleYarroch]

Fixes #1579

Risk

This PR makes minor API changes.

Testing Plan

• I have verified that I have not introduced new warnings in this PR (or explain why below)
• I have run the unit tests with this PR
• I have tested this PR against Core and verified behavior (if applicable, if not applicable, explain why below).

Unit Tests

Unit tests were added for the new alert manager classes.

Core Tests

• Send a text-field-1 only alert
• Send a text-field-2 only alert
• Send an audio file only alert
• Send a speech synthesizer string only alert
• Cancel a UI ony alert
• Cancel a speech only alert
• Cancel a UI and speech alert
• Create an alert with a duration of 10 seconds. Send the alert. Wait two seconds and send a second alert (i.e. the first alert should still be on the screen). The second alert should be sent by the alert manager after the module dismisses the first alert (i.e. 8 seconds later).
• Send an alert, modify the same alert view and send the same view 1 second later.
• Send an alert with soft buttons. Select one of the soft buttons and make sure the handler is called. Send the same alert view again and make sure the soft button handlers are called when selected.
• Send an alert with a soft button that has more than one state - an assertion should be thrown
• Send an alert with neither text, secondaryText or audio set in the SDLAlertView - a custom error should be returned in the completion handler
• Send an alert with only an audio file set in the SDLAlertView and connect to a module supporting RPC Spec version less than 5.0 - a custom error should be returned in the completion handler
