* Update PKI to natively use time.Duration
Among other things this now means PKI will output durations in seconds
like other backends, instead of as Go strings.
* Add a warning when refusing to blow away an existing root instead of just returning success
* Fix another issue found while debugging this...
The reason it wasn't caught on tests in the first place is that the ttl
and max ttl were only being compared if in addition to a provided csr, a
role was also provided. This was because the check was in the role !=
nil block instead of outside of it. This has been fixed, which made the
problem occur in all sign-verbatim cases and the changes in this PR have
now verified the fix.
* add require_cn to pki roles
* add policy_identifiers and basic_constraints_valid_for_non_ca to pki role form
* add new fields to the PKI docs
* add add_basic_constraints field
* Max role's max_ttl parameter a TypeDurationString like ttl
* Don't clamp values at write time in favor of evaluating at issue time,
as is the current best practice
* Lots of general cleanup of logic to fix missing cases
* added a flag to make common name optional if desired
* Cover one more case where cn can be empty
* remove skipping when empty; instead check for emptiness before calling validateNames
* Add verification before adding to DNS names to also fix#3918
* Start work on passing context to backends
* More work on passing context
* Unindent logical system
* Unindent token store
* Unindent passthrough
* Unindent cubbyhole
* Fix tests
* use requestContext in rollback and expiration managers
* Fix using wrong public key in sign-self-issued
* Change behavior of TTL in sign-intermediate
This allows signing CA certs with an expiration past the signer's
NotAfter.
It also change sign-self-issued to replace the Issuer, since it's
potentially RFC legal but stacks won't validate it.

* Add pki/root/sign-self-issued.
This is useful for root CA rolling, and is also suitably dangerous.
Along the way I noticed we weren't setting the authority key IDs
anywhere, so I addressed that.
* Add tests
