Change wording in different actions/steps

[dbbaughe]

Some of the steps have messages that might be unclear what they actually mean.

e.g. in transitions when the job is actively evaluating conditions before transitioning to a new state the message says "Attempting to transition" which might be understood as already evaluating to true and actively transitioning to the next state.

This issue is to go over all our messaging and come up with more clear wording to cause less confusion.

These were changed in #267, will close this for now, hopefully they are more clear but we can change them again if needed.
