Jared Biel ab54064689 Procstat input plugin - functionality for overriding of process_name (#1192) 
Being able to override the process_name in the procstat module
is useful for daemonized perl, ruby, erlang etc. processes. This
allows for manually setting process_name rather than it being set to
the interpreter/VM of the process.

Telegraf plugin: procstat

Description

The procstat plugin can be used to monitor system resource usage by an individual process using their /proc data.

The plugin will tag processes by their PID and their process name.

Processes can be specified either by pid file, by executable name, by command line pattern matching, or by username (in this order or priority. Procstat plugin will use pgrep when executable name is provided to obtain the pid. Proctstas plugin will transmit IO, memory, cpu, file descriptor related measurements for every process specified. A prefix can be set to isolate individual process specific measurements.

Example:

[[inputs.procstat]]
  exe = "influxd"
  prefix = "influxd"

[[inputs.procstat]]
  pid_file = "/var/run/lxc/dnsmasq.pid"

The above configuration would result in output like:

> procstat,name="dnsmasq",pid="44979" cpu_user=0.14,cpu_system=0.07
> procstat,name="influxd",pid="34337" influxd_cpu_user=25.43,influxd_cpu_system=21.82
