Made changes to metrics and report generation

Converted bash script to ruby
TODO:
add functionality to generate monthly data for single host
access constants/vars via command line
generate normal report.md(s) for each app, besides comparison report

Fixed small bugs

Verify you're on login node 1/3 or you won't have access to Jeff's public

Add relative time to searches
Pandoc is used to generate docx

-runs 2 monthly searches instead of 1 to generate output from scratch

library and bin/metrics altered to produce correct working path

Changed data file structure - preset data

Modified start_searches for the past month (30 days) rather than snap to last month
generate_reports.sh puts all output into data/year_month

alter generate_reports to output previous month's directory

-exits generate_reports.sh
more information during polling

small fixes

start_searches added to process 3 searches at once
generate_reports now asks for a splunk user and password

Simplify entry

See merge request !1

add stats to report generation and mkdir in generate_monthly_report to make it easier to add/rm items
