Change subject: Add three more master node to elasticsearch
......................................................................
Add three more master node to elasticsearch
This is the first step in the master node dance we're going to do to replace
the hard drives in elastic10(0[1-9]|1[0-6]). The steps are:
1. Move all data off of the nodes we're going to make master nodes.
2. Replace harddrives in these new master nodes.
3. Rebuild them as master nodes. Now we'll have 6 master nodes.
4. Remove all the data from the old master nodes.
5. Shut off elasticsearch in the old master nodes.
6. Replace their hard drives and reimagine them as non-master nodes.
We're in danger of elasticsearch split brain during step 4 but we can
limit the length of that step.
