Creating an erasure pool will crash the OSD because OSD::_make_pg
asserts if the type is not replicated. The tests related to erasure
coded pool creation are removed from qa/workunits/cephtool/test.sh.
The osd-create-pool.sh unit test covers the cases removed from test.sh
more extensively. The intent is to check the interactions with the MON
only, therefore it does not run an OSD and the absence of erasure code
placement group backend implementation is not an issue.

When osd create pool is called twice on the same pool, it will succeed
because the pool already exists. However, if a different type is
specified, it must fail.

It looked like it worked because the wrapper hide the error. The failing
tests are commented out so that the other tests can be used.

Display benchmark results for the default erasure code plugins, in a tab
separated CSV file. The first two column contain the amount of KB
that were coded or decoded, for a given combination of parameters
displayed in the following fields.
seconds KB plugin k m work. iter. size eras.
1.2 10 example 2 1 encode 10 1024 0
0.5 10 example 2 1 decode 10 1024 1
It can be used as input for a human readable report. It is also intented
to be used to show if a given version of an erasure code plugin performs
better than another.
The last column ( not shown above for brievety ) is the exact command
that was run to produce the result so it can be copy / pasted to
reproduce them or to profile.
Only the jerasure techniques mentionned in
https://www.usenix.org/legacy/events/fast09/tech/full_papers/plank/plank_html/
are benchmarked, the others are assumed to be less interesting.

instead of assuming the pool size is 2, query it and increment it to
test for pool set data size. It allows to run the test from vstart.sh
without knowing what the required pool size is in advance:
rm -fr dev out ; mkdir -p dev ; \
MON=1 OSD=3 ./vstart.sh -n -X -l mon osd
LC_ALL=C PATH=:$PATH CEPH_CONF=ceph.conf \
../qa/workunits/cephtool/test.sh

We ran into problems before when we made this a string because a mixed
cluster of mons might forward a client request with the wrong schema.
To make this work, we make the new code understand both the new and
old schema, and also backport a change to emperor and dumpling to
handle the new schema.
For the previous attempt to do this, see:

Although fsstress was being called with a static path the directory
it was writing to was in the current directory so doing a cd to the
source directory that is made in /tmp and then removing it later
caused it to be unable to write the files in a non-existent dir.
This change gets the current path first and cd's back into it after
it is done compiling fsstress.
Issue #6479.

It's legal to give a CephEntityAddr to osd blacklist with no nonce,
so allow it in the valid() method; also add validation of any nonce
given that it's a long >= 0.
Also fix comment on CephEntityAddr type description in MonCommands.h,
and add tests for invalid nonces (while fixing the existing tests to remove
the () around expect_false args).
