Major Description
As raised on the user list - https://lists.apache.org/thread/mhtj6cgf323525hs6dow1oz68nkqwfgy - users calling the Java APIs are able to get additional details on a mime type, such as common extensions and descriptions. Those calling the Tika Server can only get limited information on mime types, such as which are known to Tika
In addition to the current /mime-types endpoint (html/json/text), we should add a more detailed one that takes a specific type.
