Feature changes

• BC break: Renamed plugin configuration setting
  ini_file to config_file. In early versions the
  plugin configuration file used ini style. Back then the
  configuration setting was named accordingly. It has now been
  renamed to reflect the newer file format and to distinguish it from
  PHP’s own ini file (configuration directives file).

• Introduced new default charset setting
  server_charset to allow proper escaping before a
  connection is opened. This is most useful when using lazy
  connections, which are a default.

• Introduced wait_for_gtid_timeout setting
  to throttle slave reads that need session consistency. If global
  transaction identifier are used and the service level is set to
  session consistency, the plugin tries to find up-to-date slaves.
  The slave status check is done by a SQL statement. If nothing else
  is set, the slave status is checked only one can the search for
  more up-to-date slaves continues immediately thereafter. Setting
  wait_for_gtid_timeout instructs the plugin to poll a
  slaves status for wait_for_gtid_timeout seconds if the
  first execution of the SQL statement has shown that the slave is
  not up-to-date yet. The poll will be done once per second. This
  way, the plugin will wait for slaves to catch up and throttle the
  client.

• New failover strategy loop_before_master.
  By default the plugin does no failover. It is possible to enable
  automatic failover if a connection attempt fails. Upto version 1.3
  only master strategy existed to failover to a master if a
  slave connection fails. loop_before_master is similar but
  tries all other slaves before attempting to connect to the master
  if a slave connection fails.

  The number of attempts can be limited using the
  max_retries option. Failed hosts can be remembered and
  skipped in load balancing for the rest of the web request.
  max_retries and remember_failed are considered
  experimental although decent stability is given. Syntax and
  semantics may change in the future without prior notice.
