t0303: resurrect commit message as test documentation

Browse Source 
The commit message which added those tests (861444f 't: add test
harness for external credential helpers' 2011-12-10) provided nice
documentation in the commit message. Let's make it more visible
by putting it in the test description.

The documentation is updated to reflect the fact that
GIT_TEST_CREDENTIAL_HELPER must be set for
GIT_TEST_CREDENTIAL_HELPER_TIMEOUT to be used
and GIT_TEST_CREDENTIAL_HELPER_SETUP can be used.

test_description='external credential helper tests
This is a tool for authors of external helper tools to sanity-check
their helpers. If you have written the "git-credential-foo" helper,
you check it with:
make GIT_TEST_CREDENTIAL_HELPER=foo t0303-credential-external.sh
This assumes that your helper is capable of both storing and
retrieving credentials (some helpers may be read-only, and they will
fail these tests).
Please note that the individual tests do not verify all of the
preconditions themselves, but rather build on each other. A failing
test means that tests later in the sequence can return false "OK"
results.
If your helper supports time-based expiration with a configurable
timeout, you can test that feature with:
make GIT_TEST_CREDENTIAL_HELPER=foo \
GIT_TEST_CREDENTIAL_HELPER_TIMEOUT="foo --timeout=1" \
t0303-credential-external.sh
If your helper requires additional setup before the tests are started,
you can set GIT_TEST_CREDENTIAL_HELPER_SETUP to a sequence of shell
commands.
