feature: event interceptors

[attilaorosz]

Description

Add interceptor support on event level.

Proposed solution

Add @UserInterceptor() decorator that accepts one or more InterceptorInterface classes which would be resolved from the event container.
The interceptor should receive the socket event context and a next function. The interceptors return value should be used for the values of @EmitOnSuccess() and @EmitOnFail().
Multiple interceptors should be executed in the same order as they were provided.
