Add instructions on using compressed InnoDB tables

Add some instructions on using InnoDB table compression along with
benchmarks for optimal KEY_BLOCK_SIZE for each table.

Using binary storage and default settings for firstbits and scriptsigs,
a compression ratio of over 50% has been observed by compressing the
largest tables using the appropriate key block sizes.

Add --no-load config option

no-load skips loading blocks into the database, which is useful for a
"read-only" instance meant for serving from a shared database.

This is useful when having a dedicated instance loading blocks using
the --no-serve option so that "webserver" instances never block.
