HttpSecurityDsl should support apply method

[hanrw]

Expected Behavior

@Bean
 fun authSecurityFilterChain(http: HttpSecurity): SecurityFilterChain {
     http {
         csrf {
             disable()
         }
         cors {
             disable()
         }
         apply(LoginFilterSecurityConfigurer()) {
             jwtLogin {
                 
             }
         }
     }
     return http.build()
 }

Current Behavior

@Bean
   fun authSecurityFilterChain(http: HttpSecurity): SecurityFilterChain {
       http {
           csrf {
               disable()
           }
           cors {
               disable()
           }
           http.apply(LoginFilterSecurityConfigurer()).jwtLogin {
           }
       }
       return http.build()
   }

The apply keyword will conflict with Kotlin fun

public inline fun <T> T.apply(block: T.() -> Unit): T {
    contract {
        callsInPlace(block, InvocationKind.EXACTLY_ONCE)
    }
    block()
    return this
}

@hanrw thanks for the suggestion!

I'm not 100% sure but it seems like it will take different method parameters so it shouldn't conflict, right?

I think this would be a nice addition, so we don't need to mix a Java and Kotlin approach when using the DSL. Would you like to submit a PR?

Is 'apply' onsidered a keyword here?

The solution could be add apply function in HttpSecurityDsl

    fun <C : SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity>> apply(configurer: C): C {
        return this.http.apply(configurer)
    }

Any suggestion?

Hi @hanrw!

Any suggestion?

I think that looks like a good start. Just a heads up that if you do submit a PR, we may take a pause on merging it as most new enhancements that will make it into the next release are already scheduled.

I don't believe so, @rishiraj88. I tried something like what @hanrw provided above and it compiles fine as far as I can tell. It would just be an overloaded version of the apply method since it takes different parameters.
