[202012] Minigraph parser changes to select mmu profiles based on SonicQosProfile attribute (#11383)

Browse Source 
Signed-off-by: Neetha John <nejo@microsoft.com>

Why I did it
There is a need to select different mmu profiles based on deployment type

How I did it
There will be separate subfolders (RDMA-CENTRIC, TCP-CENTRIC, BALANCED) in each hwsku folder which contains deployment specific mmu and qos settings. SonicQosProfile attribute in the minigraph will be used to determine which settings to use. If that attribute is not present, the default settings that exist in the hwsku folder will be used
