#! @file ceph-helpers.sh
# @brief Toolbox to manage Ceph cluster dedicated to testing
#
# Example use case:
#
# ~~~~~~~~~~~~~~~~{.sh}
# source ceph-helpers.sh
#
# function mytest() {
# # cleanup leftovers and reset mydir
# setup mydir
# # create a cluster with one monitor and three osds
# run_mon mydir a
# run_osd mydir 0
# run_osd mydir 2
# run_osd mydir 3
# # put and get an object
# rados --pool rbd put GROUP /etc/group
# rados --pool rbd get GROUP /tmp/GROUP
# # stop the cluster and cleanup the directory
# teardown mydir
# }
# ~~~~~~~~~~~~~~~~
#
# The focus is on simplicity and efficiency, in the context of
# functional tests. The output is intentionally very verbose
# and functions return as soon as an error is found. The caller
# is also expected to abort on the first error so that debugging
# can be done by looking at the end of the output.
#
# Each function is documented, implemented and tested independently.
# When modifying a helper, the test and the documentation are
# expected to be updated and it is easier of they are collocated. A
# test for a given function can be run with
#
# ~~~~~~~~~~~~~~~~{.sh}
# ceph-helpers.sh TESTS test_get_osds
# ~~~~~~~~~~~~~~~~
#
# and all the tests (i.e. all functions matching test_*) are run
# with:
#
# ~~~~~~~~~~~~~~~~{.sh}
# ceph-helpers.sh TESTS
# ~~~~~~~~~~~~~~~~
#
# A test function takes a single argument : the directory dedicated
# to the tests. It is expected to not create any file outside of this
# directory and remove it entirely when it completes successfully.

# Sends a signal to a single daemon.

#
# After the daemon is sent **signal**, its actual termination

# still alive, kill_daemon will pause for a few seconds and
# try again. This will repeat for a fixed number of times
# before kill_daemon returns on failure. The list of
# sleep intervals can be specified as **delays** and defaults

# if the machine is fast enough and the daemon terminates in a fraction of a
# second. The increasing sleep numbers should give plenty of time for
# the daemon to die even on the slowest running machine. If a daemon
# takes more than a few minutes to stop (the sum of all sleep times),
