autotest: Deprecate suites directory, add suite for memory tests.

Introduce a new directory, site_tests/sequences
site_tests/suites is misleading, users are confused it with test_suites directory.

Add control file for memory qual test suite, users can call as hostless job.

BUG=chromium:398686,chrome-os-partner:33233
TEST=Check the files in sequence are build in autotest package:
equery-stumpy_moblab b control.memory_qual
 * Searching for control.memory_qual ...
 chromeos-base/autotest-server-9999
 (/autotest/server/site_tests/sequences/control.memory_qual)
CQ-DEPEND=CL:231544
Build a trybot: trybot-falco-release/R41-6531.0.0-b276
Run test_suites:hardware_storagequal_quick
(http://100.96.49.152/afe/#tab_id=view_job&object_id=24)
Check the proper tests from sequence directory are run.
Check /mnt/moblab/static/.../autotest/test_suites/suite_to_control_file_map
is correct.

Run test_suites/control.hardware_memoryqual_quick as a hostless job.
Verify memory_qual.quick control file is scheduled properly.
