Fix outdated InfluxDB configuration

Actual InfluxDB config is deprecated, it must be updated based on the
following documentation:
https://docs.influxdata.com/influxdb/v1.2/administration/config

* remove following options:
  lease-duration = "1m0s"
  pprof-enabled = false
https://github.com/influxdata/influxdb/commit/22173acb707af833b832126f8631e0afda445ea9

* rename "cluster" section to "coordination":
https://github.com/influxdata/influxdb/commit/75e89e35d80dfad65146c8d8a1df2d7b9930c99a

* remove shard-writer-timeout option:
  shard-writer-timeout = "5s"
https://github.com/influxdata/influxdb/commit/db7d58c867513d019c1b9f1718772062b5c491bc
