Change subject: [DOCS] Clarification on admission control and DDL statements
......................................................................


Patch Set 2:

> I think this is somehow much more confusing than it should be. The
 > facts are:
 > * queries submitted to a given session are executed serially, DDL
 > or not
 > * DDLs are not part of admission control
 > * Naturally, this means that any query, including DDLs, that the
 > client submits in a session that has a query queued, will not
 > execute (but this behaviour has nothing to do with admission
 > control). The tricky part is that while the example query is
 > queued, it is possible to open a new session and drop the table the
 > queued query would refer to.
 >
 > I think we should have a page somewhere (probably here?) to
 > separate these behaviours (queued due to serial exec vs queued due
 > to admission control), and spell out how this relates to DDLs
 > specifically (the scenario above is a good example IMO).

I created a new section at the end and made an attempt to address the confusion.
