39bbc66b46 Doc: create issue and PR management guidelines 
I would like to propose a formal guide for issue triage and PR management.
This should help us keep open issues and PRs under a desirable numbers.
For example, keep issues under 100. These guidelines should specially help
manage and close issues and PRs that are inactive in a timely manner.

41a0d67b30 Documentation: add links to blog post on benchmarking disks with fio 
The documentation mentions fio as a tool to benchmark disks to assess
whether they are fast enough for etcd. But doing that is far from trivial,
because fio is very flexible and complex to use, and the user must make sure
that the workload fio generates mirrors the I/O workload of its etcd cluster
closely enough. This commit adds links to a blog post with an example of how
to do that.

b5593de806 raft: Avoid multiple allocs when merging stable and unstable log 
Appending to an empty slice twice could (and often did) result in
multiple allocations. This was wasteful. We can avoid this by performing
a single allocation with the correct size and copying into it.

24f35a9861 raft: avoid allocation of Raft entry due to logging 
`raftpb.Entry.String` takes a pointer receiver, so calling it
on a loop variable was causing the variable to escape. Removing
the `.String()` call was enough to avoid the allocation, but
this also avoids a memory copy and prevents similar bugs.

This was responsible for 11.63% of total allocations in an
experiment with https://github.com/nvanbenschoten/raft-toy.
