e2e framework: add -gomega-max-length parameter

Browse Source 
When gomega.format exceeds the default size of 4000, it truncates and prints:

  Gomega truncated this representation as it exceeds 'format.MaxLength'.
  Consider having the object provide a custom 'GomegaStringer' representation
  or adjust the parameters in Gomega's 'format' package.

  Learn more here: https://onsi.github.io/gomega/#adjusting-output

These instructions don't help the user of the e2e.test binary unless we provide
a command line flag.
