governance-related docs not in governance directory

[raynamharris]

To clean up this repo, I would like to move these documents to the subdirectory called governance. Would that create any new problems?

• advisory-council.md
• executive-director.md
• governance.md
• issue-escalation.md
• membership.md
• mission-statement.md
• motion-of-no-confidence.md
• proxy-membership.md
• pursuit-of-funding.md
• steering-committee-chair.md
• strategy/strategic_plan.md

There are some inbound links to some of these from swcarpentry/website so we should just grep for those and change them to the new location when the move happens.

I'll leave them as they are.
