Description

Proposed approach: design doc

Steps

• Read about ExecPlan and ExecPlan::ToString
  • https://issues.apache.org/jira/browse/ARROW-14233
  • https://issues.apache.org/jira/browse/ARROW-15138
  • https://issues.apache.org/jira/browse/ARROW-13785
• Hook up to the existing C++ ToString method for ExecPlans
• Implement a ToString() method for ExecPlan R6 class
• Implement and document show_exec_plan()

Original description:
Now that we can print a query plan (ARROW-13785) we should wire this up in R so we can see what execution plans are being put together for various queries (like the TPC-H queries)
