I am writing a pipeline job in Jenkins which shows the output console of a downstream job in the pipeline console output. The job is working so far but the output is really hard to read due to all the echo lines added to the output by the pipeline job itself.

[Pipeline] node {
[Pipeline] echo

[Pipeline] [monitor] echo
[monitor] 
[Pipeline] [monitor] echo
[monitor] [EnvInject] - Variables injected successfully.

Is there an option, configuration, command or anything in the pipeline plugin or in Groovy or in Jenkins to allow me suppress all the extra "echoing" to make the console output more readable?

What you are really looking for is JENKINS-26124. Apparently you have some kind of workaround for this, but there is a flaw in its implementation, which we cannot see in the question.

One partial workaround specifically for your example of the

/////////////////////////////////////////////////
                Start Execution                  
/////////////////////////////////////////////////

block that you're trying to achieve is to use a single echo call on a multi-line

'''triple single quoted string''' (which could include interpolated strings as well).

From http://docs.groovy-lang.org/latest/html/documentation/#_triple_single_quoted_string,

Triple single quoted strings are multiline. You can span the content of the string across line boundaries without the need to split the string in several pieces, without contatenation or newline escape characters:

Do you need to do it via jenkins? If not you could grep it out directly from console (assuming you get the output on a linux console): 

cat YOUR_EXAMPLE_OUTPUT.txt | grep -v '\[Pipeline\]\|\[monitor\]\|^$'

that would only leave out:

/////////////////////////////////////////////////

UPDATE: if you want it "live" follow your output and pipe it into a line buffered grep: 

tail -f YOUR_EXAMPLE_OUTPUT.txt | grep -v '\[Pipeline\]\|\[monitor\]\|^$' --line-buffered

    Yes, what I want is to eliminate the extra lines in the output console as they are produced, I do not want to wait until the job is done to process/clean the output. – Miguel Leal Rosales May 02 '16 at 13:59
