When using lsf, every job queries lsf for configuration at least 3 times. This release allows to pass TOIL_CONTAINER_LSF_PER_CORE env variable with values Y/N to define if LSF total memory is define per job or per core, thus avoiding any lsf query for getting this info. And it removes the dynamic query to lsf units. It assume always that if an integer is passed to memory= then the units are bytes. If other unit is desired, it can be specified as a string. ie. memory="8Gb".
