bdevperf: config file: simplify old constructors

Browse Source 
Instead of calling bdevperf_construct_job() directly,
create a job_config instance that would express
the same semantics and then use
bdevperf_construct_config_jobs() to create and run actual jobs.
The goal is to unify methods and reduce code duplication.
