Add an entry to paramsBuilder with key-value pairing of (headerKey, fieldValue). The only
validation done is to ensure the headerKey and fieldValue are not null and non-empty. This
method is used for implicit routing headers (backwards compatibility).
Add an entry to paramsBuilder by match-and-extract field values from requests based on
pre-configured path templates. This method is called repeatedly for each configured routing
rule parameter, it's possible that the incoming field value from request is null or there is no
matches found, we'll continue the match-and-extract process for the next routing rule parameter
in such case.
