ipa: libipa: algorithm: Add queueRequest() to the Algorithm class

Browse source 
Add queueRequest() function to the Algorithm class. The queueRequest() function
provides controls values coming from the application to each algorithm.
Each algorithm is responsible for retrieving the controls associated to them.
