Clean up docs. Clean up t/pt-query-digest/since_until.t. review.t needs to be fixed and cleaned up (i.e. use pt_query_digest::main() instead of shelling out, split off --history tests into history.t, etc.).

option is used, all unique queries are saved to a database. When the
tool is ran again with L<"--review">, queries marked as reviewed in
the database are not printed in the report. This highlights new queries
that need to be reviewed. When the L<"--history"> option is used,
query metrics (query time, lock time, etc.) for each unique query are
saved to database. Each time the tool is ran with L<"--history">, the
more historical data is saved which can be used to trend and analyze
query performance over time.

is specified (see L<"--[no]create-history-table">).
pt-query-digest inspects the columns in the table. The table must have at
least the following columns:
CREATE TABLE query_review_history (
checksum BIGINT UNSIGNED NOT NULL,

naming convention. The column is special if the name ends with an underscore
followed by any of these values:
=for comment ignore-pt-internal-value
MAGIC_history_columns

If the column ends with one of those values, then the prefix is interpreted as
the event attribute to store in that column, and the suffix is interpreted as
the metric to be stored. For example, a column named C<Query_time_min> will be
used to store the minimum C<Query_time> for the class of events.
The table should also have a primary key, but that is up to you, depending on
how you want to store the historical data. We suggest adding ts_min and ts_max
columns and making them part of the primary key along with the checksum. But
you could also just add a ts_min column and make it a DATE type, so you'd get
one row per class of queries per day.
