This patch also replaces the use of {{MAX_COMPACTING_L0}} with
{{max_threshold}} in {{LeveledManifest}} - not 100% sure this is the best way
since it will increase the number of sstables needed to run STCS in L0, but at
the same time it will run actual LCS with more sstables. An alternative would
be to check if there is more than 32 ({{MAX_COMPACTING_L0}}) sstables in L0, if
so, grab {{max_threshold}} sstables and run STCS on them, wdyt [~cnlwsu]?
