make flavors use common limit and marker

Flavors REST calls were not using the common limit and 
marker function, which means that the osapi_max_limit configuration
that was set by the operator would not be respected. 

Convert flavors to use the common infrastructure thereby providing
a more consistent experience for users and operators.
