Enable HTTP v2 on Nginx container

[xr09]

Enabling HTTP v2

Enabling HTTP v2 should improve Kibana UX remarkably , HTTP v2 has many advantages over HTTP/1.1.

This change will improve Kibana loading times for all users but even more for the ones with high latency and sub-optimal connectivity (mobile networks, slow WiFis).

Currently Kibana doesn't support HTTP v2 directly so the recommended practice is using a reverse proxy. We're already using nginx exactly for that purpose so this is just a basic configuration update.

Planned changes

HTTP v2 is enabled by appending http2 on the listen configuration.

For example: listen 443 ssl http2;

Tasks

• Enable HTTP v2 on Nginx container
• Test Kibana behavior on a complete deployment
