Helm Chart corrections and additions

[KittyKatt]

Chart Additions:

• Ability to specify existing volume claim for panel pods.
• Ability to use and specify hostname for external mariadb and redis instances. This cancels creation and sourcing of the mariadb and redis subcharts.
  • Adds ability to specify database name and a password for Redis authentication should you choose one.
• Ability to specify additional annotations for Kubectyl Ingress, Service, StatefulSet, and Deployment resources.
• Full documentation on all values and defaults available in values.yaml.

Chart Fixes:

• There is no latest tag for either the panel or kuber images. This switches them to the correct develop tag.
• Splits ingress to be more sane and match the service resources.
• Corrects all ports to actually match throughout the stack and no longer requires SSL/HTTPS communication between the service endpoints and the load balancer.
• Adds some missing labels.
• Can specify timezone for panel (timezone for kuber still static to UTC).

I'll be making another PR on the source to correct the generated Kuber configuration as the above changes alone will need manual follow-up intervention to disable SSL, change the port, and use the correct sftp-server image tag.

Only after looking through https://github.com/kubectyl/panel/blob/develop/.github/docker/entrypoint.sh am I realizing that I could have just not specified an email and would have accomplished the non-encrypted nginx.conf however I do still think that would be broken.

I am of the opinion that the load balancer should handle SSL termination and that there's really no reason to add the complexity of encrypting the traffic between the load balancer and the service, so I will be keeping that in mind and modifying the the entrypoint-sh to no longer use SSL for nginx or kuber.

Perhaps this will fix the issues I was having with setting Kubectyl up. I'll spin up a cluster and see if this works - thanks!
