Allows users to customize and add additional information to Spans created by instrumentation. The typical use
case for SpanCustomizer instances is to provide proper operation names in situations where the instrumentation
is unable to generate a reasonable enough operation name, e.g. JDBC and HTTP Client calls, instead of having a
default operation name using the statement type or target host a SpanCustomizer can be provided to assign operation
names like "queryUsers" or "getUserProfile" instead.
Instrumentation wanting to take advantage of SpanCustomizers should look for an instance in the current context
using SpanCustomizer.ContextKey.
