Changes required in TorQ due to KDB-X community edition connection limits

[eohara-di]

Copied from parent issue:

KDB-X community edition only supports 8 connections per process. Several processes in the FSP use more than 8 connections, so these will need to be re-worked.

Some steps to take (either in the TorQ or FSP repo):

1. reduce number of connections made to discovery process (processes will use process.csv to connect to each other instead)
2. reduce superfluous connections e.g. segmentedtickerplant shouldn't be connected to HDB
3. remove duplicate connections if any exist
4. remove optional processes from process.csv e.g. sortworkers
