[ews] validate-change step sometimes get stuck indefinitely.

In that state, even 'Stop' button for that build doesn't work, reconnecting the worker also doesn't help. The only workaround is to restart the master.

e.g.: 
https://ews-build.webkit.org/#/builders/159/builds/11630
https://ews-build.webkit.org/#/builders/2/builds/150067
https://ews-build.webkit.org/#/builders/2/builds/149972

Note that this is happening with not just validate-change step, but various other steps like: layout-tests/run-api-tests (while consulting results database), check-status-of-pr etc.

e.g.:
https://ews-build.webkit.org/#/builders/40/builds/81557
https://ews-build.webkit.org/#/builders/41/builds/87923
https://ews-build.webkit.org/#/builders/164/builds/10537

This issue is significantly impacting EWS. About 22 out of 96 currently running builds are currently stuck because of this issue.

Day before yesterday, all  the merge-queue bots were stuck because of this issue, e.g.:
https://ews-build.webkit.org/#/builders/19/builds/29405
https://ews-build.webkit.org/#/builders/40/builds/81338
https://ews-build.webkit.org/#/builders/19/builds/29320
https://ews-build.webkit.org/#/builders/22/builds/21497
https://ews-build.webkit.org/#/builders/19/builds/29329
https://ews-build.webkit.org/#/builders/40/builds/81535

Going to restart EWS to pick up above fix.
