Change kuksa-client version handling

Does the following:

- For Docker copy whole repo so we get the expected version from tag
  (previously always 0.1.6)
- Using 0.1.6 as default version does not make sense,
  0.0.0 works better to show that version lookup failed
- Tag pattern seems to be difficult to get correct, it always complain
  and seems to have no effect
- Aligning grpcio-tools version with what is defined in setup.cfg

The reason is that all docker build on master
previously got v0.1.6 except possible if that specific version was tagged, which
gives odd behavior if downloading kuksa-client:master
