env: added support for lcore map

Browse Source 
This patch adds support for lcore mapping list, which
is needed by spdk if someone wants to use CPUs with IDs
greater than RTE_MAX_LCORE (128). For such CPUs it
is impossible to include them in the core mask (passed
to dpdk as '-c <mask>') as the dpdk doesn't allow
IDs greater than RTE_MAX_LCORE. Therefore they
must be mapped to lower lcore values using
'--lcores <maping_list>' passed to dpdk
