Add meta field to all ES filters

Prerequisite to !4391 (merged) for gitlab-com/gl-infra/scalability#1478

Apparently, the visualize app in Kibana requires a meta attribute to present. If it isn't, the query won't load on the first try, but need a refresh to load correctly.

This adds a meta component into the rison that we build for all the filters used in Kibana links.

Example dashboards:

• Error budget detail: https://dashboards.gitlab.net/dashboard/snapshot/Mf2XAymGZ6IK1ZNRf0PUeMc2WnBR4Sx2
• Web main: https://dashboards.gitlab.net/dashboard/snapshot/ERN4Z6wA5a06bpy6epNWyvsRXbrIF0Dh

Notice that in these, the links to grafana visualisations (📈) load in one click. Added bonus, because of the metadata tailored to the filter we build, the filters now display nicer in Kibana:
