Remove fixed TLS 1.2 cipher suite list and maximum TLS version so
crypto/tls can use its maintained defaults. Keep TLS 1.2 as the
minimum supported version.
Document the shared TLS default behavior for plugins that expose TLS
configuration and add coverage to ensure CoreDNS leaves Go-managed
TLS fields unset.

Enable the usetesting linter in golangci.yml configuration to
enforce proper testing practices. Replace manual temporary
directory and file creation with t.TempDir() in test files.
This improves test reliability by ensuring proper cleanup and
follows Go testing best practices.

* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
