The CLI payload syntax has some limitation, it can't handle payloads with empty lines, which is a common problem when uploading a PEM file over the CLI. This patch implements a way to customize the ending pattern of the CLI, so we can't look for other things than empty lines. A char cli_payload_pat[8] is used in the appctx to store the customized pattern. The pattern can't be more than 7 characters and can still empty to match an empty line. The cli_io_handler() identifies the pattern and stores it, and cli_parse_request() identifies the end of the payload. If the customized pattern between "<<" and "\n" is more than 7 characters, it is not considered as a pattern. This patch only implements the parser for the 'stats socket', another patch is needed for the 'master CLI'.
