* Add Request class with HTTP signature generator Spec: https://tools.ietf.org/html/draft-cavage-http-signatures-06 * Add HTTP signature verification concern * Add test for SignatureVerification concern * Add basic test for Request class * Make PuSH subscribe/unsubscribe requests use new Request class Accidentally fix lease_seconds not being set and sent properly, and change the new minimum subscription duration to 1 day * Make all PuSH workers use new Request class * Make Salmon sender use new Request class * Make FetchLinkService use new Request class * Make FetchAtomService use the new Request class * Make Remotable use the new Request class * Make ResolveRemoteAccountService use the new Request class * Add more tests * Allow +-30 seconds window for signed request to remain valid * Disable time window validation for signed requests, restore 7 days as PuSH subscription duration (which was previous default due to a bug)
