* Move the watch package into the api module
It was already just a thin wrapper around the API anyways. The biggest change was to the testing. Instead of using a test agent directly from the agent package it now uses the binary on the PATH just like the other API tests.
The other big changes were to fix up the connect based watch tests so that we didn’t need to pull in the connect package (and therefore all of Consul)
This improves the checking so that if a certificate were to expire or the roots changed then we will go into a non-ready state.
This parses the x509 certificates from the TLS certificate when the leaf is set. The readyCh will be closed whenever a parseable certificate is set and the ca roots are set. This does not mean that the certificate is valid but that it has been setup and is generally valid. The Ready function will now do x509 certificate verification which will in addition to verifying the signatures with the installed CA roots will also verify the certificate isn't expired or not set to become valid in the future.
The correct way to use these functions is to wait for the ReadyWait chan to be closed and then periodically check the readiness to determine if the certificate is currently useable.
There are also a lot of small bug fixes found when testing lots of things end-to-end for the first time and some cleanup now it's integrated with real CA code.
- Includes some bug fixes for previous `api` work and `agent` that weren't tested
- Needed somewhat pervasive changes to support hash based blocking - some TODOs left in our watch toolchain that will explicitly fail on hash-based watches.
- Integration into `connect` is partially done here but still WIP
