Add new rate-based disk and network pipelines

Addresses: BP rates-derived-from-cumulative

Add new pipeline config to derive rate-based gauge meters
from the current set of cumulative disk and network meters
gathered by the compute agent.

The latter form of meter is not suitable for alarming
against a static threshold, whereas rate-based meters would
allow for example autoscaling actions to be driven off the
observed per-second rates of I/O.

assertTrue(isinstance) replace by assertIsInstance

some of tests use different method of assertTrue(isinstance(A, B))
or assertEqual(type(A), B). The correct way is to use
assertIsInstance(A, B) provided by testtools

use six.move.xrange replace xrange

in python3.x, there is no method named xrange(),
it has replaced by range(),which is equal to xrange()
in python2.x. so we must fix this issue.
we use six moduleto fix this issue.
