test: add integration tests for EC disk type support 

Add integration tests to verify the -diskType flag works correctly:
- TestECDiskTypeSupport: Tests EC encode and balance with SSD disk type
- TestECDiskTypeMixedCluster: Tests EC operations on a mixed HDD/SSD cluster

The tests verify:
- Volume servers can be configured with specific disk types
- ec.encode accepts -diskType flag and encodes to the correct disk type
- ec.balance accepts -diskType flag and balances on the correct disk type
- Mixed disk type clusters work correctly with separate collections
