Describe the bug

The environment variable KC_CACHE_EMBEDDED_MTLS_ENABLED is always evaluating to its default value, false.

In the CacheManagerFactory class, the condition

Configuration.isTrue(CachingOptions.CACHE_EMBEDDED_MTLS_ENABLED_PROPERTY)

is always set to false.

The problem is that the kc. header, known as NS_KEYCLOAK_PREFIX, isn't being added to the string when being evaluated. A workaround for this problem is to use CACHE_EMBEDDED_MTLS_ENABLED, without the KC_ prefix.

To fix this, there are two potential solutions.

1. Add the NS_KEYCLOAK_PREFIX to the Configuration.isTrue(String) method.
   Change

public static boolean isTrue(String propertyName) {
        return getOptionalBooleanValue(propertyName).orElse(false);
    }

to

public static boolean isTrue(String propertyName) {
        return getOptionalBooleanValue(NS_KEYCLOAK_PREFIX + propertyName).orElse(false);
    }

2. Use Configuration.isTrue(Option) instead in CacheManagerFactory.
   Change

if (Configuration.isTrue(CachingOptions.CACHE_EMBEDDED_MTLS_ENABLED_PROPERTY)) {
            ...
        }

to

if (Configuration.isTrue(CachingOptions.CACHE_EMBEDDED_MTLS_ENABLED)) {
            ...
        }

Regression

• The issue is a regression

Expected behavior

By setting KC_CACHE_EMBEDDED_MTLS_ENABLED to true, the log message MTLS enabled for communications for embedded caches should appear

Actual behavior

Since it's always defaulting to false, the log message doesn't appear and TLS doesn't get properly set up.

How to Reproduce?

Set the environment variable KC_CACHE_EMBEDDED_MTLS_ENABLED to true, and the MTLS enabled logging message will not appear.
