Tools repo ownership

[Matt Caswell]

Following the discussion in PR 58 [1] about the ownership of the tools
repo, I've started an OMC vote to see the tools repo split into "tools"
and "omc-tools", with some tools moving to omc-tools. OMC would have
commit/approval rights for omc-tools, and the OTC would have
commit/approval rights for tools.

I'll report back here once the vote is complete.
