-User must provide a mapping file via new --sample_rename_mapping_file argument.
Mapping file must contain a mapping from absolute bam file path to new sample name
(format is described in the docs for the argument).
-Requires that each bam file listed in the mapping file contain only one sample
in their headers (they may contain multiple read groups for that sample, however).
The engine enforces this, and throws a UserException if on-the-fly renaming is
requested for a multi-sample bam.
-Not all bam files for a traversal need to be listed in the mapping file.
-On-the-fly renaming is done as the VERY first step after creating the SAMFileReaders
in SAMDataSource (before the headers are even merged), to prevent possible consistency
issues.
-Renaming is done ONCE at traversal start for each SAMReaders resource creation in the
SAMResourcePool; this effectively means once per -nt thread
-Comprehensive unit/integration tests
Known issues: -if you specify the absolute path to a bam in the mapping file, and then
provide a path to that same bam to -I using SYMLINKS, the renaming won't
work. The absolute paths will look different to the engine due to the
symlink being present in one path and not in the other path.
