[TRAFODION-2626] Fix DCS API for $TRAF_LOG

Previous change allowed configuration of log location, but did not

take into account retrieving logs via DCS web interface.

Link to trafodion logs is not exposed by default, but this change was tested

with that option enabled, as well as default.

[TRAFODION-3164] Restart mxosrvrs on-demand

This code adds a zookeeper value to signal to mxosrvr processes

when it is time to exit. This allows to phase out processes when

things in the environment change. The process will wait until it

is idle before exiting.

Keepalive could be configured by modifying file src/main/java/org/trafodion/dcs/Constants.java

[TRAFODION-2245] Multiple sqcheck and jps processes running when monitor is downed and up as dcsserver checks if trafodion is up

A new option sqcheck -n <nid> is introduced to determine if the node is up and running

rather than at the time of starting the processes

Also fixed the failure of hive/TEST018 due to expected file difference
