MCP-server: Multi-tenancy support

[ov-developer]

Hi!

We would like to use mcp-security, but the lack of multi tenancy support is a blocker for us.
Currently the issuerUrl must be configured, but this is not feasable for us, as we create tenants dynamically.
Are there any plans yet to support OAuth2 with multi tenancy?

https://docs.spring.io/spring-security/reference/servlet/oauth2/resource-server/multitenancy.html

e.g.

oauth2ResourceServer {
    authenticationManagerResolver = JwtIssuerAuthenticationManagerResolver.fromTrustedIssuers(::isTrustedIssuer)
}
