Aaron Lehmann c44e7a3e63 Pass upstream client's user agent through to registry on operations beyond pulls
This adds support for the passthrough on build, push, login, and search.

Revamp the integration test to cover these cases and make it more
robust.

Use backticks instead of quoted strings for backslash-heavy string
contstands.
