* Allow OpenSSH-style key type identifiers
To bring better parity with the changes of #14008, wherein we allowed
OpenSSH-style key identifiers during generation. When specifying a list
of allowed keys, validate against both OpenSSH-style key identifiers
and the usual simplified names as well ("rsa" or "ecdsa"). Notably, the
PKI secrets engine prefers "ec" over "ecdsa", so we permit both as well.

* Use rsa-sha2-256 as the default SSH CA hash algo
As mentioned in the OpenSSH 8.2 release notes, OpenSSH will no longer be
accepting ssh-rsa signatures by default as these use the insecure SHA-1
algorithm.
For roles in which an explicit signature type wasn't specified, we
should change the default from SHA-1 to SHA-256 for security and
compatibility with modern OpenSSH releases.

* Allow specifying multiple allowed SSH key lengths
In the ssh secrets engine, only a single allowed key length was allowed
for each algorithm type. However, many algorithms have multiple safe
values (such as RSA and ECDSA); allowing a single role to have multiple
values for a single algorithm is thus helpful.
On creation or update, roles can now specify multiple types using a list
or comma separated string of allowed values:
allowed_user_key_lengths: map[string][]int{"rsa": []int{2048, 4096}}

* Forbid ssh key signing with specified extensions when role allowed_extensions is not set
- This is a behaviour change on how we process the allowed_extensions role
parameter when it does not contain a value. The previous handling allowed
a client to override and specify any extension they requested.
- We now require a role to explicitly set this behaviour by setting the parameter
to a '*' value which matches the behaviour of other keys such as allowed_users
within the role.
- No migration of existing roles is provided either, so operators if they truly
want this behaviour will need to update existing roles appropriately.
* Add support for templated values in SSH CA DefaultExtensions.
* Reworking the logic per feedback, adding basic test.
* Adding test, so we cover both default extension templating & ignoring default when user-provided extensions are present.
* Fixed up an unintentional extension handling defect, added test to cover the case.
* Refactor Default Extension tests into `enabled` and `disabled`.

gRPC doesn't have a handler for recovering from a panic like a normal
HTTP request so a panic will actually kill Vault's listener. This
basically copies the net/http logic for managing this.
The SSH-specific logic is removed here as the underlying issue is caused
by the request forwarding mechanism.
Adding a boolean field that determines whether users will be allowed to
set the ID of the signed SSH key or whether it will always be the token
display name. Preventing users from changing the ID and always using
the token name is useful for auditing who actually used a key to access
a remote host since sshd logs key IDs.
