Shared Worker Executors

[MikeEdgar]

While doing some debugging, I noticed based on the number of threads in the JVM that there are two shared worker executor pools used:

• kubernetes-ops-pool
• kubernetes-ops-tool

My gut reaction was that it's a typo and only pool should be created, but I wanted to check before opening an issue.

Nice typo. There seem to be also many sections of the code running blocking executions not using the pool ... they should all use it.

(pool is the right one of course)
