go/neo/t/neotest: Add bench-local and bench-cluster commands

These commands do full benchmarking for localhost and networked cases:

- show system info
- do server & client cpu benchmarks
- do server disk benchmarks
- for networked case: do network benchmarks
- tail to either zbench-local or zbench-cluster

It was full `neotest bench-local` that was used to prepare benchmarks
for http://navytux.spb.ru/~kirr/neo.html and http://navytux.spb.ru/~kirr/misc/neo·P4.html
