…cy to the performance-diagnostic package (#85)

Initial addition of configuration and control files to enable
performance metric collection using the Telegraf agent.
See also IDEA-2835 : Improving Support Bundle Performance Metrics

Includes:
- Service definition and startup script for "delphix-telegraf"
- Modified version of "estat" adding JSON output via a "-j" option
- A "perf_playbook" wrapper script to enable/disable enhanced collection
- Configuration file sections (combined on startup)
- Simple wrappers to facilitate parsing of "nfs_threads", "zpool iostat -o",
and "zcache stats -a" outputs

The service starts with a "base" set of metrics, but will include Object Storage
metrics when it is detected, and will include Performance Playbook commands
if that has been enabled (manually). The config is reassembled each startup.

File paths intended:

/opt/delphix/server/bin/delphix-telegraf-service
/lib/systemd/system/delphix-telegraf.service
/etc/telegraf/nfs-threads.sh
/opt/delphix/server/bin/perf_playbook
/etc/telegraf/telegraf.base
/etc/telegraf/telegraf.inputs.dose
/etc/telegraf/telegraf.inputs.playbook
/etc/telegraf/zcache-stats.sh
/etc/telegraf/zpool-iostat-o.sh

This configuration records 4 output files (rotated on size) for main metrics,
aggregate statistics (min,max,mean,stddev) and Playbook outputs to enable
independent retention periods.
