The ThreadPoolExecutor on the DotConcurrentFactory should have a name

[jdotcms]

Currently when the ThreadPoolExecutor rejects a thread looks like:

ent.DotConcurrentException: Task java.util.concurrent.FutureTask@4f4d36fd rejected from java.util.concurrent.ThreadPoolExecutor@582bbe5[Running, pool size = 50, active threads = 50, queued tasks = 100, completed tasks = 45322]
at com.dotcms.concurrent.DotConcurrentFactory$DotConcurrentImpl.submit(DotConcurrentFactory.java:475) ~[dotcms_5.3.8_999999.jar:?]

That do not give us info about which pool is having the issue, including the name would be a bit easier

We need to, by default, make the DotConcurrentFactory queue unbounded as is the java default. We can message in the logs / warn if the queue grows to over a specific size, e.g. over 50k or 100k, but we should not error out. The queue size has bitten us a number of times already.

Note: This fix basically just changes the default value.

For existing systems, the solution is to change the value of DOTCMS_CONCURRENT_QUEUECAPACITY (DOT_DOTCMS_CONCURRENT_QUEUECAPACITY when setting via env var) to a (much) higher value, like 100000.

I would suggest even higher, something like 1,000,000,000. The java default is 2,147,483,647
