Zack Zatkin-Gold 61be19b1f0 Fix telegraf example arguments (#2788) 
Many of the examples provided within documentation are using a single
dash for the command line arguments, but the telegraf executable
explicitly has two dashes.

There are also some inconsistencies with the ordering of the command
line argument examples.  I've ordered them so that the examples will
show: config, config-directory, input-filter, test

Mesos Input Plugin

This input plugin gathers metrics from Mesos. For more information, please check the Mesos Observability Metrics page.

Configuration:

# Telegraf plugin for gathering metrics from N Mesos masters
[[inputs.mesos]]
  ## Timeout, in ms.
  timeout = 100
  ## A list of Mesos masters.
  masters = ["localhost:5050"]
  ## Master metrics groups to be collected, by default, all enabled.
  master_collections = [
    "resources",
    "master",
    "system",
    "agents",
    "frameworks",
    "tasks",
    "messages",
    "evqueue",
    "registrar",
  ]
  ## A list of Mesos slaves, default is []
  # slaves = []
  ## Slave metrics groups to be collected, by default, all enabled.
  # slave_collections = [
  #   "resources",
  #   "agent",
  #   "system",
  #   "executors",
  #   "tasks",
  #   "messages",
  # ]

By default this plugin is not configured to gather metrics from mesos. Since a mesos cluster can be deployed in numerous ways it does not provide any default values. User needs to specify master/slave nodes this plugin will gather metrics from.
