PostgreSQL: __unixEpochGroup to support arithmetic expression as argument (#46764) 
* __unixEpochGroup to support arithmetic argument

Following call generates wrong expression : 
 
$__unixEpochGroupAlias(height+42,$__interval)

=> floor(height+42/60)*60 AS "time"

instead of

=> floor((height+42)/60)*60 AS "time"

* Update test of __unixEpochGroup related to issue #46764

Sven Klemm c3aad10047 change timescaledb to checkbox instead of select 2018-08-09 10:05:35 +02:00
Sven Klemm b987aee7cf add timescaledb option to postgres datasource 
This adds an option to the postgres datasource config for
timescaledb support. When set to auto it will check for
timescaledb when testing the datasource.

When this option is enabled the $__timeGroup macro will
use the time_bucket function from timescaledb to group
times by an interval.

This also passes the datasource edit control to testDatasource
to allow for setting additional settings, this might be useful
for other datasources aswell which have optional or version
dependant features which can be queried.

This adds a new fill mode last (last observation carried forward) for grafana
to the sql datasources. This fill mode will fill in the last seen value in a
series when a timepoint is missing or NULL if no value for that series has
been seen yet.
