Make ACME EAB keys specific to the ACME directory they are created within (#20803)
* Update EAB management urls underneath pki/eab

 - It was decided that for ease of ACLing, the management
   paths for EAB apis should be outside of the acme path
   prefix
 - Delete duplicated tests, rely on the proper cluster
   based tests for EAB management.

* Update ACME EAB creation paths to be directory specific

 - Make the EAB creation APIs directory specific.
 - This commit is still missing the enforcement that
   they can be redeemed on a specific path.

* Enforce EAB tokens per ACME directory context like accounts

 - Do not allow an EAB from one ACME directory to be used
   in another.
 - Rework the ACME directory function to simply get the path from the request instead of parsing out the role/issuer name.
 - Add some commentary around expectations if operators change issuer names

* Add an EAB certbot integration test

 - Verify with the 3rd party certbot cli that our EAB workflow works as expected.

* Fix unit test

 - Unit test wasn't setting up r.Path within the request
   that we now use to determine the acme directory.

Add External Account Binding support to ACME (#20523)
* Add Vault APIS to create, list, delete ACME EAB keys

 - Add Vault authenticated APIs to create, list and delete ACME
   EAB keys.
 - Add supporting tests for all new apis

* Add require_eab to acme configuration

* Add EAB support to ACME

* Add EAB support to ACME

* PR feedback 1

 - Address missing err return within DeleteEab
 - Move verifyEabPayload to acme_jws.go no code changes in this PR
 - Update error message returned for error on account storage with EAB.

* PR feedback 2

 - Verify JWK signature payload after signature verification

* Introduce an ACME eab_policy in configuration

 - Instead of a boolean on/off for require_eab, introduce named policies for ACME behaviour enforcing eab.
 - The default policy of always-required, will force new accounts to have an EAB, and all operations in the future, will make sure the account has an EAB associated with it.
 - Two other policies, not-required will allow any anonymous users to use ACME within PKI and 'new-account-required' will enforce new accounts going forward to require an EAB, but existing accounts will still be allowed to use ACME if they don't have an EAB associated with the account.
 - Having 'always-required' as a policy, will override the environment variable to disable public acme as well.

* Add missing go-docs to new tests.

* Add valid eab_policy values in error message.

Move all ACME wrappers into a dedicated go file (#20174)
* Move all ACME wrappers into a dedicated go file

 - Make it easier to figure out where the various wrappers for
   ACME exist by locating them inside a dedicated go file instead
   of spread out across the various path_acme_xxx files.

Add ACME authorizations & challenges (#20113)

* Add ability to load and save authorizations

Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>

* Add ACME authorizations path handling

This supports two methods: a fetch handler over the authorization, to
expose the underlying challenges, and a deactivate handler to revoke
the authorization and mark its challenges invalid.

* Add ACME challenge path handling

These paths kick off processing and validation of the challenge by the
ACME client.

Use a UUID for ACME kid instead of a key fingerprint (#20110)
* Use a UUID for ACME kid instead of a key fingerprint

* PR feedback

 - Calculate thumbprint within CreateAccount instead of passing it in
 - Reorder writes within CreateAccount to now write out thumbprint entry
   first as we can easily recover/overwrite it if we fail mid-way
 - Change back LoadAccount in acme to return an error if it fails to
   lookup the entry

* Clearify comment within ACME CreateAccount

Add acme account storage (#19953)
* Enable creation of accounts

 - Refactors many methods to take an acmeContext, which holds the
   storageContext on it.
 - Updates the core ACME Handlers to use *acmeContext, to avoid
   copying structs.
 - Makes JWK exported so the JSON parser can find it.

* Finish ACME account creation

 - This ensures a Kid is created when one doesn't exist
 - Expands the parsed handler capabilities, to format the response and
   set required headers.

Merge ACME package back into the PKI package (#19826)
* Squash pki/acme package down to pki folder

Without refactoring most of PKI to export the storage layer, which we
were initially hesitant about, it would be nearly impossible to have the
ACME layer handle its own storage while being in the acme/ subpackage
under the pki package.

Thus, merge the two packages together again.

* Properly format errors for missing parameters

When missing required ACME request parameters, don't return Vault-level
errors, but drop into the PKI package to return properly-formatted ACME
error messages.
