Run_wrapper.rst was missing some command line arguments. Added additional args in the file. Included all initial review comments.

This looks pretty good, save for some minor nitpicks below. I also echo Maíra's comments, though I'm not _too_ worried about having a little bit of duplication if it means we get a complete (or nearly-complete) list of arguments here, but still have them described in the appropriate part of the rest of the documentation.

Instead, enable all tests which have satisfied dependencies by adding ``CONFIG_KUNIT_ALL_TESTS=y`` to your ``.kunitconfig``. +- ``--kunitconfig``: Specifies the path to the ``.kunitconfig`` file.
- This Kconfig fragment enables KUnit tests. The "/.kunitconfig" gets
- appended to the path specified. For example, If a directory path "lib/kunit"
- is given, the complete path will be "lib/kunit/.kunitconfig".
This is definitely a bit confusing: it seems to describe "how it works" more than "what is it, and when do you use it". Perhaps something more like:
"Specifies a .kunitconfig file to use to build and run with a predefined set of tests and their dependencies. (e.g., to run tests for a given subsystem). This can be the path to a file, or to a directory (in which case a file named ".kunitconfig" in said directory will be used.)"
+- ``--kconfig_add``: Specifies additional configuration options to be
- appended to the ``.kunitconfig`` file. For example, ``CONFIG_KASAN=y``.
+- ``--arch``: Runs tests with the specified architecture. The architecture
- specified must match the string passed to the ARCH make parameter.
- For example, i386, x86_64, arm, um, etc. Non-UML architectures run on QEMU.
- Default to 'um'.
+- ``--cross_compile``: Specifies the Kbuild toolchain. It passes the
- same argument as passed to the ``CROSS_COMPILE`` variable used by
- Kbuild. This will be the prefix for the toolchain
- binaries such as GCC. For example:
- ``sparc64-linux-gnu`` if we have the sparc toolchain installed on
- our system.
This example should be ``sparc64-linux-gnu-`` (with the extra hyphen-minus at the end). It's concatenated to produce, e.g., sparc64-linux-gnu-gcc.
- ``$HOME/toolchains/microblaze/gcc-9.2.0-nolibc/microblaze-linux/bin/microblaze-linux``
- if we have downloaded the microblaze toolchain from the 0-day
- website to a specified path in our home directory called toolchains.
+- ``--qemu_config``: Specifies the path to the file containing a
- custom qemu architecture definition. This should be a python file
- containing a QemuArchParams object.
+- ``--qemu_args``: Specifies additional QEMU arguments, for example, "-smp 8".
+- ``--jobs``: Specifies the number of jobs (commands) to run simultaneously.
- By default, this is set to the number of cores on your system.
+- ``--timeout``: Specifies the maximum number of seconds allowed for all tests to run.
- This does not include the time taken to build the tests.
+- ``--kernel_args``: Specifies the kernel command-line arguments. Might be repeated.
Nit: maybe "Specifies _additional_ kernel command-line arguments". kunit_tool already sets some.
+- ``--run_isolated``: If set, boots the kernel for each individual suite/test.
- This is useful for debugging a non-hermetic test, one that
- might pass/fail based on what ran before it.
+- ``--raw_output``: If set, generates unformatted output from kernel.
- If set to ``--raw_output=kunit``, filters to just KUnit output.
--raw_output=kunit is the default if just --raw_output is set. You need to specify --raw_output=all for the full kernel output.
+- ``--json``: If set, it stores the test results in a JSON format and prints to stdout or
- saves to a file if a filename is specified.
Nit: let's remove the first 'it' to be consistent with the previous entries. i.e., "If set, stores..."
