Improved support for DNOS/FTOS M-Series (#8749)

Current implementation for Force10 series doesn't support the switch-blade M-Series model. This PR adds support for mempools and temperature. In my test environment (still 1.31) I have processors utilization support as well, but I have to test that in the new way processors are handled since 1.37
