web.page.* functionality that allows to send http headers with curl

Steps to reproduce:

Use web.page.get to get some prometheus metrics from an openshift cluster that requires bearer auth. This would allow monitoring of metrics just using the agents deployed by the openshift zabbix operator. Else the zabbix server or proxy must be in the same network to be able to access the metric endpoints, as they are by default only available on the internal network.

Result:
Not possible currently because there is no way to send the bearer auth with web.page.get.

Expected:
Ability to specify header info like the Bearer Token to authenticate with the openshift metrics exporters by simply using the zabbix agents installed by the openshift zabbix operators.
