Implements a kompose specific docker compose label "kompose.service.expose" which can be used to expose the specified services externally. The accepted values are of type string.
If the value is set to "true", the provider sets the endpoint automatically, and for any other value, the value is set as the hostname. If multiple ports are defined in a service, the first one is chosen to be the exposed.
Unit tests, functional tests, glide updates and docs have also been added in this commit for the related feature.
When kompose convert -o artifacts is run, then if artifacts is a directory,
kompose stores all the resulting files inside it, and if it's not a directory,
it stores the artifacts in a single file.
Fixes#209
if a user specifies a docker-compose service
with restart value as "no" or "on-failure"
then normal pod will be created as against
to a controller and a pod.
Now a user can provide volumes_from to share volumes
from other service so here the PVC created for that
service will be shared by service calling volumes_from
Now a user can select a provider using global flag
--provider=openshift to select openshift provider
or --provider-kubernetes to select kubernetes provider
if nothing is provided kubernetes is the default provider.
Fixes#179
