Add support to WT_SESSION::alter to change table log setting

We want to be able to alter the table setting to allow a table to toggle the setting about whether or not it is logged. This setting may likely require that the URI not be open at the time of the change so that it is known to be in a durable state.

Test ideas: Write some data that we can search for in printlog output. Toggle the setting back and forth, adding data and detecting whether it is or is not in the log output. Try to alter an in-use table, we should get back an error, probably EBUSY. Test toggling system-wide use of logging as well.
