a sequence of ConfigBlock objects
This could in principle just be a simple python list, and maybe we
change it to that at some point (10 Mar 22). Having it as its own
class allows to implement some helper functions.
This implements an interface similar to ConfigBlock, but it
doesn't derive from it, as ConfigBlock will likely gain
functionality in the future that wouldn't work for a sequence (or
wouldn't work in the same way).

Check for blocks with dependencies.
If a block required another block that is not present, will
throw an error; Otherwise, will move block immediately after
required block. If dependency is not required, will move
after other block, if it is present.
Note: this implementation can only move blocks forward.

set the given option on the sequence
The name should generally be of the form
"groupName.optionName" to identify what group the option
belongs to.
For simplicity I also allow a ".optionName" here, which will
then set the property in the last group added. That makes it
fairly straightforward to add new blocks, set options on them,
and then move on to the next blocks. Please note that this
mechanism ought to be viewed as strictly as a temporary
convenience, and this short cut may go away once better
alternatives are available.
WARNING: The backend to option handling is slated to be
replaced at some point. This particular function may change
behavior, interface or be removed/replaced entirely.
