* Port over some SP v2 bits
Specifically:
* Add too-large handling to Physical (Consul only for now)
* Contextify some identity funcs
* Update SP protos
* Add size limiting to inmem storage
Add missing Headers field, along with a test to detect changes.
The custom decoder test should be ensuring only that the resulting
OpenAPI JSON outputs are equal. Updating the go-test deep library
reveals the error.
* First pass at filtered-path endpoint. It seems to be working, but there are tests missing, and possibly some optimization to handle large key sets.
* Vendor go-cmp.
* Fix incomplete vendoring of go-cmp.
* Improve test coverage. Fix bug whereby access to a subtree named X would expose existence of a the key named X at the same level.
* Add benchmarks, which showed that hasNonDenyCapability would be "expensive" to call for every member of a large folder. Made a couple of minor tweaks so that now it can be done without allocations.
* Comment cleanup.
* Review requested changes: rename some funcs, use routeCommon instead of
querying storage directly.
* Keep the same endpoint for now, but move it from a LIST to a POST and allow multiple paths to be queried in one operation.
* Modify test to pass multiple paths in at once.
* Add endpoint to default policy.
* Move endpoint to /sys/access/filtered-path.
* Implemented a warning when tls_cipher_suites includes only cipher suites which are not supprted by the HTTP/2 spec
* Added test for cipher suites
* Added hard fail on startup when all defined cipher suites are blacklisted. Added warning when some ciphers are blacklisted.
* Replaced hard failure with warning. Removed bad cipher util function and replaced it by external library.
* Added missing dependency. Fixed renaming of package name.
