Issue 51054 - Revise ACI target syntax checking
Bug Description: The previous commit enforced a strict syntax that was previously
allowed. This is causing regressions for customers and community
members.
Fix Description: Reject ACI's that use more than one equal sign between the target
keyword and the value, but do not enforce that the values are
quoted. A flag was added that we can turn on strict syntax at a
later date, but for now we will continue allow values without quotes.
