perf: Use spdk_env_opts struct to parse args

Browse Source 
When perf tool parses CLI arguments, it saves
each argument to a global value. Later these
values are checked for non-zero and copied to
spdk_env_opts structure. It can be simplified
by saving parsed arguments directly to env_opts
structure. It is applicable to env options only,
options specific for perf are still copied to
global variables.
