[SPARK-12699][SPARKR] R driver process should start in a clean state
Currently we have R worker process launched with the --vanilla option that
brings it up in a clean state (without init profile or workspace data,
https://stat.ethz.ch/R-manual/R-devel/library/base/html/Startup.html). However,
the R process for the Spark driver is not.
We should do that because
1. That would make driver consistent with the worker process in R - for
instance, a library would not be load in driver but not worker
2. Since SparkR depends on .libPath and .First() it could be broken by
something in the user workspace, for example
Here are the changes proposed:
1. When starting `sparkR` shell (except: allow save/restore workspace,
since the driver/shell is local)
2. When launching R driver in cluster mode
3. In cluster mode, when calling R to install shipped R package
This is discussed in PR #10171
