Introduce variable for total events with no tries limit

[tvami]

I am updating ldmx-sw, here are the details.

What are the issues that this addresses?

This resolves #1299

Check List

• I successfully compiled ldmx-sw with my developments
• I ran my developments and the following shows that they are successful.

I ran the pn code and set

p.run = 2
p.maxEvents = 1

• In default I get

Started 23 events to produce 1 events.

• then

p.maxEvents = 1
p.maxTriesPerEvent = 10

leads to

Started 10 events to produce 1 events.

• then

p.maxEvents = 1
p.maxTriesPerEvent = 10
p.totalEvents = 1

leads again to

[ Process ] 2 : The totalEvents was set, so maxEvents and maxTriesPerEvent will be ignored!
Started 23 events to produce 1 events.

as expected

This looks good, I would just ask for the totalEvents config option to be added to the python config class documentation and include reference to it in the max* descriptions since they will be ignored if it is used.

ldmx-sw/Framework/python/ldmxcfg.py.in

Lines 330 to 334 in 11d6a8e

	maxEvents : int
	Maximum number events to process
	maxTriesPerEvent : int
	Maximum number of attempts to make in a row before giving up on an event
	Only used in Production Mode (no input files)

Thanks Tom, I've changed those points
