This command will add `kompose command` used to generate artifacts as well as `kompose version`,
for ex,
```
metadata:
annotations:
kompose.cmd: kompose convert -f /home/snarwade --stdout
kompose.version: 1.0.0 (HEAD)
```
For functional test, Now each test has template like,
```
"annotations": {
"kompose.cmd": "%CMD%",
"kompose.version": "%VERSION%"
```
Because, for every machine these values will be different.
Updated functional test with new annotations
This PR uses the "SelectorFromSet()" function which takes alabel or
selector as an argument returns all the object that uses that label or
selector. Once we get the object that uses a particular label we can
further do the delete operation on them. This is similar to "kubectl
delete <object> --selector=<key>=<value>". Also the label has been
modified from service to io.kompose.service.
If TCP is passed in as the protocol, by default, we add TCP as the
protocol within the Kubernetes or OpenShift artifacts.
By default, TCP is already selected within Kubernetes and thus having
the TCP output is redundant.
This commit checks to see if TCP has already been selected, and if it
has, ignores adding it to the list of ports.
Closes https://github.com/kubernetes-incubator/kompose/issues/392
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.
