Subject: [PATCH] dashboard: set InfluxDB default policy to autogen

`default` InfluxDB policy keyword cannot be used as a value in raw
InfluxDB queries. `autogen` retention policy is created by default [1]:

  When you create a database, InfluxDB automatically creates a retention
  policy called autogen with an infinite duration, a replication factor
  set to one, and a shard group duration set to seven days

thus it is well-suited to be a default value.

Part of #143
