Ceph paxos propose interval

When a command is sent to the Ceph monitor, such as ceph osd pool create, it will add a pool to the pending changes of the maps. The modification is stashed for paxos propose interval seconds before it is used to build new maps and becomes effective. This guarantees that the mons are not updated more than once a second ( the default value of paxos propose interval ).
When running make check changing the paxos propose interval value to 0.01 seconds for the cephtool tests roughly saves half the time (going from ~2.5mn to ~1.25mn real time).
