v0.4.0

• Added some dashboards documentation (currently 4 dashboards)
• Added Postgres datasource and 'pdb_vars' tool to use it.
• Made Grafana connections to postgres and Influx DB read-only/select-only (using new ro_user).
• Added full automatic deploy support (CD - continuous deployment), can also be used manually
• Added handling of [deploy] and [no deploy] flags
• Added OPA project
• Made Home dashboard content Postgres variable, so only one place to update
• Added conditional content support in Postgres partials (to insert content depending on for example hostname)
• Added all tables documentation, and all main devstats aspects documentation
• Added option to copy Influx database from the test server (on the production) using select only user. This allows avoiding local generation of InfluxDB on production deploy. Speedup deployment 100x.
• Imported new cncf/gitdm affiliations
• Updated histograms to display all actors even with single activity, they were cut at 3 or 5 before that.
• Added NATS project

• Added 'User reviews' dashboard.

• Added 'PR workload' and 'PR workload table' dashboards.
• Made 'idb_tags' multithreaded using anonymous closure go routine - big speedup.
• Added 'Reviews/LGTMs per user/repo' dashboard
