[compress] Add range request control option

[masaori335]

Prior to the change, the range-request config controls compress plugin to skip compression if Range request. However, this makes unexpected behavior once the object is cached without Range request.

To fix the case, this removes Range header if client send both of Accept-Encoding and Range header.

Update: add new options to choose Accept-Encoding header or Range header if a client sends both headers.

• ignore-range (or true) : Remove Range header
• no-compression: Remove Accept-Encoding header
• none (or false): do nothing
