Web interface ZBX_SERVER_HOST and ZBX_SERVER_PORT are missing by default

[ypicard]

Describe the bug
When deploying the chart for the first time with zabbixweb enabled, the dashboard complains about the zabbix server not being available on localhost.

It is because the default values of ZBX_SERVER_HOST and ZBX_SERVER_PORT (https://github.com/cetic/helm-zabbix/blob/master/templates/deployment-zabbix-web.yaml#L47) for the web service are not set in values.yaml for zabbixweb (https://github.com/cetic/helm-zabbix/blob/master/values.yaml#L231).

I have made it work by manually setting them to the following:

ZBX_SERVER_HOST: zabbix-zabbix-server
ZBX_SERVER_PORT: 10051

Hi @ypicard!

Thanks for report this issue.

This problem is solved using other approach in PR #54, that will not use this variables. Righ @sa-ChristianAnton?

@ypicard, if you have some time, could you take a look at this PR?

We are close to finalizing the tests and adjustments to publish version 3.0.0 of the helm chart which changed very significant changes.
