Description

Currently we have this task https://issues.apache.org/jira/browse/ARROW-14233 However, that task is very open about the scope. So this ticket will try to address some improvements for ExecPlan::ToString without the need to have additional sophistication nor to extend the scope of features for ExecPlan::ToString.

This means that we won't need to research about GraphViz (or other backends) here. We will just need to work to have these features for ExecPlan::ToString:

• Print index/Id for each node  in the physical tree
• Make sure all the nodes have names and correct index/IDs
• Apply indentation for the printing process (this may be an optional setting in the API)
