Brace yourselves! For there are many touched files here. No changes
in semantics however.
Spent a long time trying out the various optional rules gocritic
provides, and settled for a few of them. There are more I really
like, but that would take many hours to address across the codebase.
Perhaps others find gocritic too pedantic? If so, we can merge the
fixes without enabling the rule.

Additionally, improve the JWT verification process when a JWKS
is provided:
* If `kid` is present in JWT header, and exists in JWKS — verify using
that key only.
* If `kid` not present in JWT header, try verification only using keys
matching the `alg` provided in the JWT header (mandatory claim).
Fixes#4699

This package is deprecated, archived, and in maintenance mode, since Go
errors support wrapping natively.
For #2152.

These changes add support for digital signatures for policy bundles which
can be used to verify their authenticity.
Bundle signature verification involves the following steps:
* Verify the JWT signature
* Verify the files in the JWT payload exist in the bundle
* Verify the file content of the files in bundle match with those in the payload
This commit adds a new `sign` command to generate a digital signature for policy bundles.
For more details, run "opa sign --help"
The signatures generated by the 'sign' command can be verified by the
'build' command. The 'build' command can also sign the bundle it generates.
The 'run' command can verify a signed bundle or skip verification altogether.
OPA 'sign', 'build' and 'run' can be used to
sign/verify bundles in bundle mode (--bundle) mode only. Verification
can be also be performed when bundle downloading is enabled.
Fixes: #1757
