[TRAFODION-2628] Updates for elasticity

Replaced the list of CPU (node) numbers with an array, since it is

really a mapping array from logical to physical numbers.

Also changed some code in the adaptive segmentation code, but it is

likely that Adaptive Segmentation will not work (with or without my

change), this is not turned on by default and is not tested.

[TRAFODION-2628] SQL engine work for Elasticity

It turns out that the compiler already kept a list of node ids,

not assuming that node ids are consecutively numbered 0...n-1.

However, this list was contained in lots of other data structures

that are dead code, coming from the time before Trafodion was

open-sourced. The change does two things: a) getting rid of obsolete

info and b) maintining a list of node ids in the NAClusterInfo

class.

This change does not include executor modifications. The executor

might work just fine, or we may need to add a fix (or optimization)

for cases where we pick a node id for a new process at runtime.
