Change the ownership to hpo instead of root for all copied files in Dockerfile

Description: This fixes the issue #99

From the docker references, the default behavior of docker is to copy with root unless chown flag is used.

Attaching the snapshot from that document and reference:

All new files and directories are created with a UID and GID of 0, unless the optional --chown flag specifies a given username, groupname, or UID/GID combination to request specific ownership of the copied content.

Reference: https://docs.docker.com/engine/reference/builder/#copy

Ownership of files with new changes in Dockerfile:

[hpo@d5bf819453e0 app]$ ls -lrt
total 12
-rw-rw-r--. 1 hpo hpo   79 Sep 23 17:04 requirements.txt
-rw-rw-r--. 1 hpo hpo 1448 Sep 23 17:04 index.html
-rw-rw-r--. 1 hpo hpo  512 Sep 23 17:04 experiment.html
drwxr-xr-x. 5 hpo hpo   57 Sep 23 19:15 src

Able to validate the same in openshift quicklab cluster. PFB logs:

[saakhan@saakhan hpo]$ kubectl get pod -n openshift-tuning
