ad0af9fff5 vm: return Report from MonitorExecution 
This allows callers to get access to Report.Corrupted.
Better than adding 6-th return value and will allow
to pipe other report properties if necessary.

2d24bbb225 vm/gce: fix nil deref 
New console output code crashes with nil deref,
because we shadow outer err variable and then
dereference nil err.

Also express ssh connect timeout in real time.
Currently the timeout is on par of ~25 mins
(5s sleep + 10s connect timeout) * 100.
Reduce timeout to 5m of real time.

4bd78cef05 pkg/report, pkg/repro, syz-manager: name crash attributes consistently 
We currently have several names for crash attributes, which is disturbing.

Title - single line bug identity.
Report - whole crash text.
Log - whole fuzzer/kernel output.
