[pablochacin]

Execution time is between 4 and 5 minutes, affecting developers' productivity

time make e2e

real	4m13,408s
user	1m24,239s

Presently, the e2e cluster creation time is around 60s. If we add the time needed for the setup of each individual test (for example, deploy and expose an application) the total time for the setup rises to around 90s.

Some approaches that can be tried:

• #179
• #191
