Dinesh Bhor 212d254da1 Remove 'on_shared_storage' parameter from nova evacuate 
Starting since version 2.14, Nova automatically detects whether the
server data is on shared storage or not.

Removed 'on_shared_storage' parameter from nova evacuate call and
bumped nova api version from 2.9 to 2.14 so that shared storage
deployment can be detected by nova. Also added a related note in
README.rst to point out. Operators should configure shared storage
to use maskari otherwise instance data will be lost after evacuation.

Masakari

Virtual Machine High Availability (VMHA) service for OpenStack

Masakari provides Virtual Machine High Availability (VMHA) service for OpenStack clouds by automatically recovering the KVM-based Virtual Machine(VM)s from failure events such as VM process down, provisioning process down, and nova-compute host failure. It also provides API service for manage and control the automated rescue mechanism.

NOTE: Use masakari only if instance path is configured on shared storage system i.e, 'instances_path' config option of nova has a path of shared directory otherwise instance data will be lost after the evacuation of instance from failed host if, * instance is booted from image * flavor using ephemeral disks is used
