Fixes #70 .
Introduced "codec" parameter to the
teragrep exec hdfs save
command. It will take a String as the value. Parsing of that value will happen in PTH-10 and the requirements for that is documented to PTH-10 #280. The idea is to give the user the possibility to use a specific codec for the compression of saved files and PTH-10 will check if that codec is valid for the format chosen in the command.Unit tests include a general test for using all parameters together as well as a basic test for using the codec parameter.
