Report active spring profile

Problem Statement

Our Spring Boot integration could report active spring profiles by default.

This may help customers find issues with profiles not being applied or having the wrong profile active for any environment.

Solution Brainstorm

Adding this to our sample app:

  @Bean
  public SentryOptions.BeforeSendCallback beforeSendCallback(Environment environment) {
    return (event, hint) -> {
      event.setTag("active-spring-profiles", Arrays.toString(environment.getActiveProfiles()));
      return event;
    };
  }

produces the following in an event with SPRING_PROFILES_ACTIVE=eu-staging:

    "tags":
    {
        "my-partition-tag": "europe-tag",
        "active-spring-profiles": "[eu-staging]"
    },

and the following without any active profile:

    "tags":
    {
        "active-spring-profiles": "[]"
    },

We could replace the empty array with "default" instead.

We should not be using tags directly from the SDK, we're planning to add it to a new context "spring".
