Add configuration options for compressing the whole dir

* COMPRESSED_PATH env var can be used to define where to store the
archive created. By default the archive is stored in the root of
the gather directory
* DELETE_AFTER_COMPRESSION env var can be used to define whether the
uncompressed files are deleted after the compression is done. By
default the uncompressed files are also kept. If DELETE_AFTER_COMPRESSION
is set to 1 then the files are deleted.
