* 1011: Added SuppressWarnings for SonarCloud errors
All of these files are causing SonarCloud to report the following error:
Loops should not be infinite
Since these instances all require an infinite loop that will never end,
these warnings should be disabled so that SonarCloud no longer reports
them as error.
The rule is: squid:S2189
* 1011: Made all of the randoms static and final
According to SonarCloud rule: "Random" objects should be reused, randoms
should not be recreated. This commit has taken all of the Randoms and made
them constant variables in the files that are using them.
