Add ability to specify a path on Ingress objects for Jira and Confluence helm charts.

[Atchuu]

Adding the ability to specify a path to the ingress templates for both Jira and Confluence. The templates and were changed in such a way as to be backwards compatible while allowing the ability to specify a path if desired.

Hi @Atchuu
Thank you so much. We rarly use context paths, so we didnt implement it. But it should, so thank you.

I will test this as soon as possible.

Hi @Atchuu

From the viewpoint of helm and ingress, this pull request is fine.

The problem is that it only deals with the kubernetes side of the task. We still need to make the change to server.xml.

If i could get you to do those changes as well, and thereby finishing the taks we can do the merge.

Changes needs to be done to server.xml for both jira and confluence as per this guide :
https://confluence.atlassian.com/jirakb/change-the-context-path-used-to-access-jira-server-225119408.html

in the docker-entrypoint.sh script found here
https://github.com/Praqma/jira/blob/master/docker-entrypoint.sh and
https://github.com/Praqma/confluence/blob/master/docker-entrypoint.sh

The problem with merging it without that change is, that people will get confused as to why it doesnt work.
