1. Support replacing cache compressor …

   This commit adds support for replacing the compressor used for
   serialized cache entries.  Custom compressors must respond to `deflate`
   and `inflate`.  For example:
   
     ```ruby
     module MyCompressor
       def self.deflate(string)
         # compression logic...
       end
   
       def self.inflate(compressed)
         # decompression logic...
       end
     end
   
     config.cache_store = :redis_cache_store, { compressor: MyCompressor }
     ```
   
   As part of this work, cache stores now also support a `:serializer`
   option.  Similar to the `:coder` option, serializers must respond to
   `dump` and `load`. However, serializers are only responsible for
   serializing a cached value, whereas coders are responsible for
   serializing the entire `ActiveSupport::Cache::Entry` instance.
   Additionally, the output from serializers can be automatically
   compressed, whereas coders are responsible for their own compression.
   
   Specifying a serializer instead of a coder also enables performance
   optimizations, including the bare string optimization introduced by cache
   format version 7.1.
