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 does a major refactor on the compose.go functions as well as brings
in a new era of v3 support to Kompose.
Similar to how we utilize libcompose, we utilize docker/cli's "stack
deploy" code which has a built-in v3 parser. We convert the parsed
structure to our own and then convert it to Kubernetes/OpenShift
artifacts.
