Title: add support for docker {pull,tag}, and, finally, for app import command

With this PR it is possible to import app container from built-n-ready container foreign docker repository:
```bash
$ cocaine-tool app import \
--container-url=foreign-registry.host/container-name \
--docker-address=http://localhost:12345 \
--manifest='{"slave":"/something"}' \
--registry=cocaine-registry \
--name=something_blabla_v1518
```
It's going to be useful for migrating containers from testing cluster to production.
