Code Issues Proposed changes

support retry operation task of v2 API

Browse Source 
This patch implements retry operation task defined in ETSI NFV-SOL003
v3.3.1 5.4.14.

Basically retry operation is not task API specific. Thus retry
operation of a task API which is added in the future (ex. scale)
will be supported naturally.

Functional tests will be provided with another patch.

Implements: blueprint support-nfv-solv3-error-handling
