Problematic quotes in HTCondor

[mambelli]

Describe the bug
2 issues involving quotes in HTCondor configuration and ClassAds

1. Glideins logs StartdLog had errors like:

CONFIGURATION PROBLEM: Failed to insert ClassAd attribute TRUST_DOMAIN = myhost.domain.org:9618?sock=collectorRANDOM.  The most common reason for this is that you forgot to quote a string value in the list of attributes being added to the STARTD ad.

Probably because the TRUST_DOMAIN was considered a condor expression.
NOTE that in 2018 HTCondor required to change TRUST_DOMAIN config macro from string to expression
Todd T. said that quotes should not be required and to contact them with details and an easy way to reproduce the error.
2. Startd ads are new in 23.9 (instead of slot ads). In Glideins ClassAds Tim T saw quotes with strings that are not in standalone installations ClassAds. This is a change of behavior, and needs to be verified

To Reproduce
Run smoke test for the first one. Use HTCondor 23.9 for the second.

Expected behavior

Cole (HTC team) said that TRUST_DOMAIN seems to be a string. He will follow up.
