Fix #169
page.goto timeout needs to be aligned to query timeout in remote server mode.

Thanks for this PR. Have tested this with a dashboard with some long-running queries and could recreate the original issue. This PR worked as expected.

@daniellee this is still not available over grafana-cli. Are you going to add it there? What about the signature? Thanks!

@mjtrangoni we had some problems publishing the new version due to changes to our publishing pipeline. (The image renderer plugin is so much bigger than all the other plugins and adding plugin signing). Will hopefully have that resolved soon.
