…y installed data from a previously inactive data node. - Support special exceptions to the sdt.conf variable (in the [download] section) max_parallel_download_per_datanode, the maximum number of parallel downloads for any datanode. A new [download] variable, max_parallel_download_special_datanodes, allows different variables for specified data_nodes. The full data_node name does not have to be specified; a substring will do. For example: max_parallel_download_special_datanodes=crd-esgf-drc:3, tropmet:1

Sometimes, notably for CCCma, a data node enforces a maximum number of simultaneous connections, which differs from what we would want for most data nodes. To transfer data from such a node, we need a special node-dependent value of max_parallel_download. That is what this patch enables. To use it, set max_parallel_download_special_datanodes in the download section of the configuration file. The value is a comma-separated list of special datanodes and values (separated with a colon) such as:
max_parallel_download_special_datanodes = crd-esgf-drc:3, tropmet:1
Note that the full datanode url or name is not required; you only need a substring.
