InfluxDB 1.7.9 authentication setting for /debug/vars access

[timhallinflux]

Feature Request

Need new, optional settings for InfluxDB v1 plugin to allow for authenticated access to /debug/vars.
username/password must be supplied if the the InfluxDB config pprof-auth-enabled = true is set.

Proposal:

Please add this support to the InfluxDB v1 plugin.

Reproducing/testing notes: In order for pprof-auth-enabled to be enabled, auth-enabled and pprof-enabled must also be set to true.

  auth-enabled = true
  pprof-enabled = true
  pprof-auth-enabled = true

The requested functionality is already supported by including the username/password into the url in the config (must use this method as a separately defined username and password may not apply to every url defined in the list.

urls = ["http://user:pass@localhost:8086/debug/vars"]

I'm leaving this open so we can sanitize the logs.

I assume that this endpoint supports HTTP Basic Auth. If so we should add a username and password option for this and not use or recommend the userinfo section of the URL, as its use was deprecated long ago.
