update to mocking code
Change signature of stop method.

Passing a boolean is now deprecated in favour of a hash, this
change is introduced to keep fog forward compatible with api
changes and to make the fog api more consistent.
Add support for expunging node in cloudstack.

The method takes a hash, if expunge is set to true in that hash
the vm is expunged immediately. Expunge is false by default.
Make job polling requests for Dyn retryable within exconn by passing the idempotent option.

[GH-2873] Ensure fog is using fog-core 1.22+

fog-v1.22.0 went out with the dependencies loosely defined so it would
accept fog-core-v1.21.

fog/fog-core@e164cc7 removed a Vsphere helper method than had been
incorrectly defined on the Fog module. This was then extracted into
fog-core.

The fix was applied to `fog` already but the dependencies allow the
incorrect version of fog to run with the cleaned up version of fog-core
whilst they should not.
