This patch provides a base to support multi version API.
The existing code of functions for SOL specification was hard to
understand and enhance since it is based on the code of legacy tacker
API and they are connected with each other complicatedly.
Therefore the code for SOL specification is newly created which
is independent to the legacy tacker API so that it will be easy to
maintain and enhance.
This patch supports vnflcm v2 API (api_version 2.0.0) as a starting
point. It supports less functions than the exsisting v1 API at the
moment(Xena) but it will catch up with by the next release (Y).
This patch makes supporting another API version easy when it will
be supported in the future. Possibly it may thought to add v1 API to
this code base.
TODO: enhance UT/FT
UT/FT is not sufficient at the moment. Additional UTs and FTs will
be provided with another patches.
