Split slower tests to a separate test target
If a test binary didn't change in a CL, ATP will skip running it. Right
now, all update engine unittests are packed into a single target called
update_engine_unittests. This is bad, as any changes in code will cause
this test binary to change, triggering re-run of all test cases.
This CL splits some of the HTTP related testcases to a separate test
target. We rarely change HTTP related code, and these test cases take a
long time to run. For majority of code changes that don't touch HTTP,
ATP should be able to skip running HTTP testcases and save us time.
Test runtime:
1. http unitests: 3min
2. all other update_engine unitests: 3min
