Increased OS_TEST_TIMEOUT in .testr.conf to 700

Default OS_TEST_TIMEOUT is 500s, but for the test
test_user_update_own_password this is not enough
because by default in MCP the user_lockout_duration
is 600s, so the test is sleepning for 600s and not
finished, but it is stopped by testr. Increasing
of OS_TEST_TIMEOUT to more than user_lockout_duration
helps the test to pass.
