Implementation of SSL caching; tests in separate CL.

This CL adds the ability for a SSLAdapter to resume a previous session, saving a roundtrip and significantly reducing the # of bytes needed to bring up the new session.

To do this, the sessions need to share state. This is addressed by introducing the SSLAdapterFactory object, which can maintain a SSL_CTX and session cache for multiple sessions.

This CL does not have unit tests in order to minimize the change size (i.e., to reduce the size of the CP). CL https://chromium-review.googlesource.com/c/558612 builds on this CL and adds tests, but makes some nontrivial changes to SSLStreamAdapter in order to get the test server to share a SSL_CTX across sessions.
