RFE: Abstract the commandline options for the command used for kdump_core_collector

[tyll]

Currently the kdump_core_collector accepts values such as makedumpfile -l --message-level 2 -d 30 that we demo in presentations. Since the system roles are also about abstractions, it would make sense to expose the command-line options for makedumpfile as individual variables, especially the bitmap specified after -d could be exposed as the following booleans:

• kdump_dump_zero_pages
• kdump_dump_non_private_cache
• kdump_dump_private_cache
• kdump_dump_user_data
• kdump_dump_free_pages

And a sensible default could be used.

Without looking at the details, the proposal sounds reasonable. @baoquan-he what do you think?
