alternate alias names based on the service accounts's namespace and
name

* Update github.com/ulikunitz/xz

Fixes known security vulnerability GHSA-25xm-hr59-7c27.
* Update github.com/ulikunitz/xz
* Added security advisory ID to changelog.
The previous version of `go-discover` pulled in a broken version of
`tencentcloud-sdk-go`, resulting in anything that runs `go get -d`
downstream breaking... ie, a dep on hashicorp vault will break
Dependabot (among other things).
I already fixed it in `go-discover`, so this just pulls in the update.
More details in
657e803ce0
and https://github.com/hashicorp/go-discover/issues/172.

Unlike the other libraries that were migrated, there are no usages of
this lib in any of our plugins, and the only other known usage was in
go-kms-wrapping, which has been updated. Aliasing it like the other libs
would still keep the aws-sdk-go dep in the sdk module because of the
function signatures. So I've simply removed it entirely here.

This adds a random string generation library that validates random
strings against a set of rules. The library is designed for use as generating
passwords, but can be used to generate any random strings.
* Don't use string formatting to prepare queries.
We should, when possible, use the built-in params and ? format when
preparing and executing a query. This is done to prevent SQL Injection
attacks.
* Revert some changes due to failing tests, update mssql go driver
* Add docker container startup for some MSSQL tests
* Remove acceptance test flagging, add more SQL injection protection
* Refactor MSSQL prepareTestContainer to a test helper
Also, remove all ? references and convert them to @p*
This addresses an issue found in #8696 which was determined to be due to
the Go module proxy having a cached copy of a tag that doesn't match the
official version (due a build prep error weeks ago). All of the repos
got new patch versions, but the content is identical.
The commit I'm interested in is
googleapis/google-cloud-go@fbf2f51 ,
which disables an aggressive 2-second timeout for awaiting headers from
the compute metadata service.
This 2-second timeout causes problems when [Workload Identity] is
enabled on a cluster. In this situation, a different endpoint is used
under the hood for compute metadata, and this endpoint can often take
more than 2 seconds to return headers.
[Workload Identity]: https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity

I'm not sure if it's that Go has worked around/fixed this or Apache did,
but I can confirm that it builds fine with both Go 1.12.13 and 1.13.4
without the line.
Based on Vault changelog JWT-71 and JWT-77 should be included in Vault
1.3.0. Unfortunetly there was a wrong version of vault-plugin-auth-jwt
included.
