Kubernetes Opex Analytics 0.4.2

This is a maintenance release with the following changes:

• Added compatibility with Kubernetes Security Context in order to run Kubernetes Opex Analytics's pods in unprivileged mode by default (i.e. programs inside the containers are executed under a non-root user account). This change fixes issue #15. However to avoid regression due to resources (e.g. files) created with former versions where containers were executed in privileged mode, it's still possible to launch the pods in privileged mode. In this latter case you need to edit the Helm values.yaml file and set the variable securityContext.enabled accordingly. It must be set with a boolean value, true to run pods in unprivileged mode and false otherwise.
• Misc improvements on uwsgi startup process.

Enjoy.

• PR #21: Fixed date parsing for the frontend; this actually allows to also handle epoch timestamp.
• Fixed issue #20: Cleaning Bearer token in proxy mode, what lead to unauthorized access from Kubernetes API.
