Subject: [PATCH v2 2/3] kunit: tool: factor exec + parse steps into a function
Currently this code is copy-pasted between the normal "run" subcommand
and the "exec" subcommand.
Given we don't have any interest in just executing the tests without
giving the user any indication what happened (i.e. parsing the output),
make a function that does both this things and can be reused.
This will be useful when we allow more complicated ways of running
tests, e.g. invoking the kernel multiple times instead of just once,
etc.
We remove input_data from the ParseRequest so the callers don't have to
pass in a dummy value for this field. Named tuples are also immutable,
so if they did pass in a dummy, exec_tests() would need to make a copy
to call parse_tests().
Removing it also makes KunitParseRequest match the other *Request types,
as they only contain user arguments/flags, not data.
