565f787bb3 Add pkg/logwrite which writes and rotates log files 
This process connects to memlogd and streams logs to individual files,
one per log. It keeps track of how many bytes have been written to each
file and rotates when the file size exceeds a defined threshold.

By default the maximum size of each file before rotation is 1MiB and
we keep up to 10 files per log.

177008fe0c tests: Temporarily disable containerd test 
Looks like brtfs-prog v4.17 as shipped with alpine:3.8 requires
a loopback device of 109MB while the containerd tests only
create a 100MB device. This causes the test to fail.

Disable it until https://github.com/containerd/containerd/issues/2447
is fixed.

6aca715ad8 memlogd: replace an unbounded buffer with bounded channel 
Previously we had a per-connection

  bytes.Buffer // to be written to the connection
  sync.Cond    // to allow us to Wait for more data

This had the major disadvantage that the buffer was unbounded and so
a slow client could cause memory exhaustion in the server. This patch
replaces these with a single

  chan *logEntry

which is naturally bounded and supports blocking read. We make write
non-blocking using select i.e. we drop messages rather than allocate
more space.
