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 adds support for building and pushing docker containers
when you perform either `kompose convert` or `kompose up`.
Docker Compose files who have build parameters with their respective
image and build keys will automatically be both built and pushed.
now args provided under build in docker-compose file can be available in buildconfig.
it solves #406
Added unit test and functional test
solves #445
