initial implementation of the logstor storage engine for key-value tables that supports writes, reads and basic compaction. main components: * logstor: this is the main interface to users that supports writing and reading back mutations, and manages the internal components. * index: the primary index in-memory that maps a key to a location on disk. * write buffer: writes go initially to a write buffer. it accumulates multiple records in a buffer and writes them to the segment manager in 4k sized blocks. * segment manager: manages the storage - files, segments, compaction. it manages file and segment allocation, and writes 4k aligned buffers to the active segment sequentially. it tracks the used space in each segment. the compaction finds segment with low space usage and writes them to new segments, and frees the old segments.
Scylla in-source tests.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
