Verifying this change

Follow this checklist to help us incorporate your contribution quickly and easily:

• Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
• Format the pull request title like [ISSUE #123] Fix UnknownException when host config not exist. Each commit in the pull request should have a meaningful subject line and body.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add integration-test in test module.
• Run mvn -B clean package apache-rat:check findbugs:findbugs -Dmaven.test.skip=true to make sure basic checks pass. Run mvn clean install -DskipITs to make sure unit-test pass. Run mvn clean test-compile failsafe:integration-test to make sure integration-test pass.

Should we add an new plugin implemetation for oidc?

ui adapt should be merged.

Should we add an new plugin implemetation for oidc?

if you are talk about https://nacos.io/docs/v2/plugin/auth-plugin, it seems like is Authorization Plugin, but this is Authentication implementation.

I've referenced the LDAP implementation, which is implemented through user and password, but OAuth is a completely different authentication method, and requires redirection and acceptance of information callback endpoint.

[KomachiSion]

The LDAP is implemented before nacos support auth plugin, so it bind with default plugin implementation.
In fact, LDAP Plugin also should extract and move into nacos-plugin.

So should OIDC plugin implement in nacos-plugin? Or some reason which OIDC plugin must bind with defualt plugin?
