Go through existing panels on https://wikimedia.biterg.io and check/decide which ones are not relevant for Wikimedia's needs and remove them.

As per 2017-03-24:

• Overview
  • Kill columns related to mailing lists and MediaWiki in favor of T116572: Add remaining KPIs to Overview once available in kibana, once ready. Those widgets are on the respective ML and MW dashboards already.
• Git
  • "Commits by Timezone" (git_commits_timezone) feels unimportant but I'm unwilling to maintain a downstream change ([[ https://github.com/grimoirelab/panels/blob/master/doc/dashboard-customization.md | C_ ]]) for this. Hence keep/ignore.
• Gerrit
• Gerrit-Backlog
• Mailing Lists
• IRC
  • "Last messages" and "Word Frequency" lists feel unimportant but I'm unwilling to maintain a downstream change ([[ https://github.com/grimoirelab/panels/blob/master/doc/dashboard-customization.md | C_ ]]) for this. Hence keep/ignore.
• Git-Demographics
  • Kill "Git Summary" (git_main_numbers), already on Git dashboard
• MediaWiki
  • "Last edits" and "Last created" lists feel unimportant but I'm unwilling to maintain a downstream change ([[ https://github.com/grimoirelab/panels/blob/master/doc/dashboard-customization.md | C_ ]]) for this. Hence keep/ignore.
• Maniphest
  • "Assigned Organizations" (maniphest_issues_organizations_assignee, the pie chart) feels less interesting.
• Maniphest Backlog
  • Potentially remove "Accumulated Time (days): Issues waiting to be closed" (maniphest_openissues_accumulated_backlog_time)? I don't see much useful information in that...
• Maniphest Timing
  • Kill "Backlog" (maniphest_backlog) list of all items - no good use for us.
  • (Submitters is duplicated from Maniphest but useful for filtering)
