[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

DCS server is changed to use this option when it detects the server is gone

rather than at the time of starting the processes

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

[TRAFODION-1784]remove closed statement from HashMap

[TRAFDOION-1784][MTDCS]statement shoud be removed from HashMap when it's closed.

TrafConnection uses a HashMap to store the statements in MTDCS code.

When a statement is closed, it should be removed from the HashMap,

otherwise the JVM garbage collection couldn't delete the unused objects.

[TRAFODION-1682]MT-DCS protocol issue fix

This commit will fix following issues.

1. [TRAFODION-1682][MTDCS] ODBC: SQLFetch returned invalid cursor

state. It's caused by the length of descriptor2List is not correct and

the sqlQueryType is not correct either. For sqlQueryType,

SqlUtils.getSqlStmtType(String str) will be used instead of

SqlUtils.getSqlStmtType(int stmtType) since it can't return the

correct value.

2. [TRAFODION-1653][MTDCS] coast tests core dumped at 'operator new'

when Multithread DCS is on. It's caused by the EndTransaction message

missing a int which indicate 0 excaption when there is no exception.

3. [TRAFODION-1658][MTDCS] with MultiThread DCS on, coast core dumped

at memcpy when there is parameter in prepare statement. It's caused by

the length of the descriptor2List is not correct.
