Suraj Narwade ec897ef50f Added dockerfile key support
Fixes #486
This commit will add `dockerfilepath` key under Dockerstratergy in buildconfig.
dockerfilepath allow us to use dockerfiles which are named different than `Dockerfile` which are placed in context directory.

for example, for a docker-compose file:

```
version: "2"
services:
    foo:
        build:
            context: "./build"
            dockerfile: "Dockerfile-alternate"
        command: "sleep 3600"
```
Resulting buildconfig will be:

```
apiVersion: v1
kind: BuildConfig
...
...
  strategy:
    dockerStrategy:
      dockerfilePath: Dockerfile-alternate
    type: Docker
...
...
```
