29ad037125 demo: Remove jq and sfdisk from etcd image 
They are no longer needed as the mounting happens in the
mount container.

9ee52aa966 Rework how /var is mounted 
Instead of mounting a new filesystem, revert to doing a `rw` bind.

However do not make `/` `rshared`, just `/var` as that is where we expect
filesystems to be mounted for persistence. Also only make the actual
container rootfs writeable, not the whole directory.

2bd75a621d demo: Switch etcd bootstrap from discovery service to static IPs 
This makes the configuration simpler but requires us to be able
to set IP addresses on instances.

This also, for simplicity, reduces the number of nodes to 3.

The script does not make assumption about specific IP addresses,
but does assume that the nodes have IP addresses such as:
a.b.c.200, a.b.c.201, and a.b.c.202.

f5306b23ef miragesdk: fix the fork/exec init code and add a test 
Make all the low-level init code synchronous to avoid weird blocks on `close`.
Also move the net and ctl file descriptor at the beginning of the fd space for
the calf.

The SDK also allow to spamn multiple exec calves, which will all have the same
fd map:

- 0: stdin  = /dev/null
- 1: stdout = pipe to parent stdout
- 2: stderr = pipe to parent stderr
- 3: net    = socketpair to parent "net" pipe
- 4: ctl    = socketpair to parent "ctl" pipe
