We now refuse to start more than one monitor on the same machine if
hostnetworking is enabled.
Supporting this creates a lot more complexity from the rook side. Also
having 3 monitors running on the same machine is not a production setup.

This means multi-cluster support on the same machine
is not possible anymore when hostnetworking is enabled.

ceph: no longer create fallback osd

Rook's behavior should not be to create a default OSD in dataDirHostPath
when no devices are present on a node. Any preexisting fallback osd
should be kept as long as no dirs or disks have been specified to keep
the legacy behavior for those clusters running with these osds in place.
The legacy deletion behavior is also kept, removing the osd as soon as
any dir or device is specified other than the dataDirHostPath dir.

pkg: timeout ceph commands

Following Golang conventions, I'm adding the missing comments on
the constants and exported functions.
Signed-off-by: Sébastien Han <seb@redhat.com>

The Ceph CLI has the flag option '--connect-timeout' which controls the
timeout of the command when reaching out to a monitor. If the connection
cannot be established within 15 seconds, the command will fail. The
default value in Ceph is relatively long (300sec IIRC). This is a
problem when monitors have trouble reaching out quorum, since this means
the command will only fail after 300 sec.
Now we fail faster.

mon: do not generate nor inject a monmap

Given that we have mon_host and mon_initial_members sections in our
ceph.conf, building a monitor map is not needed. During the monitor mkfs
a monmap will get generated on the fly based on the section mentioned
above.

One benefit from that commit is a potential speed improvement as we have
removed the container that was generating the map from the monitor
initialization sequence.

The Endpoint has a format such as ip:port and the comment was implying

ceph/osd: send log output to stderr

The io.MultiReader(r1, r2) reads r1 until EOF before moving on to r2.
When used for stdout/stderr stderr will not be written to the log until
stdout reaches EOF. This patch reads stderr in a go routine so that the
two streams can be interleaved properly.
