Abillity to enable/disable specific sub-modules - this settings do not
affect system tables which are allways persisted,cached and written to
commitlog
enable-in-memory-data-store marks if tables will be written/read to/from
disk
enable-commitllog marks if tables will be written to commitlog
enable-cache marks if tables will be written/read to/from cache
Please note in-memory-data-store does not change the read path so "old"
sstables are still read and cache may be used to cache their data

syslogd supprt from Avi:
Allow log output to go to syslog, from where it can be shipped to journald/
some other machine/splunk/whatever. Disabled by default, exposed via config.
config.hh changes rapidly, so don't force lots of recompiles by including it.
Need to place seed_provider_type in namespace scope, so we can forward
declare it for that.
To handle the fact that --data-file-directories is supposed to be 1+
folders.
Note that boost::program_ops already "reserves" the use of std::vector
as reciever of values for multitoken options (i.e. those with more than
one value). Thus, values recieving a list of tokens via command line
should adhere to the multi-token rules, i.e. space separated values.
End result is that --data-file-directories now accept multiple paths,
white space separated,
i.e. --data-file-directories <path1> <path2>
And as it turns out, this is really a nicer way of writing stuff than
using "," or ":" seperation of paths etc, so...

* Allow boost::config to translate string_maps via iostream
* Special case seed_provider (struct) into two parameters (for lack of a
good way to express it on command line)

* Based on the property set of cassandra 2.1
* Structure mapping all "known" cassandra.yaml config properties
* YAML and command line parsing of opts.
* Tracks is-set? and set-from-where?
* Uses giant macros to make Avi happy.
