chore: Update to go 1.17 and update deps

[jkayani]

Description

Updates deps and updates to using go 1.17. Some special things to call out:

• IBM SM SDK removed the CertificateSecretData struct they were using to return cert data for public_cert and imported_cert secret types; it has been replaced with a map[string]interface{} which simplifies our code. Code and tests updated, and confirmed to work in an e2e test.

• Google gnostic library was moved across repos which go doesn't seem to understand yet. Fixed with the suggestion given here Error parsing go.mod module declares its path as: github.com/google/gnostic but was required as: github.com/googleapis/gnostic google/gnostic#262

• The Vault auth libraries for approle and userpass have a weird revision that Go doesn't seem to understand. It is fixed in main but not any of the stable released tags. Please backport #13321 to 1.9.x branch hashicorp/vault#13528

• Should address CVE-2021-43998 for Vault (though I don't think we exposed the vulnerable code here) and seems to remove the ulikuntiz/xz dep to handle CVE-2020-16845

Other information

I guess the go 1.17 changes the format of this file to include 2 require() blocks, not sure what that's about yet

[jkayani]

Because the number of explicit requirements may be substantially larger in an expanded Go 1.17 go.mod file, the newly-added requirements on indirect dependencies in a go 1.17 module are maintained in a separate require block from the block containing direct dependencies.
