If quotes in the values of the Gerrit change parameters sent to the build should be escaped or not.

E.g.
  GERRIT_CHANGE_SUBJECT=Fixed "the thing"
 will be processed to :
  GERRIT_CHANGE_SUBJECT=Fixed \"the thing\"

Triggers configured before this setting was introduced (gerrit-trigger < v. 2.2.1) will have this unchecked, giving the same behavior as before by leaving the quotes as is.
