You can also modify the behaviour of the `TraceFilter` - the component that is responsible
for processing the input HTTP request and adding tags basing on the HTTP response. You can customize
the tags, or modify the response headers by registering your own instance of the `TraceFilter` bean.

add to the Span a tag with key `custom` and a value `tag`.
