Handle special characters in CpsPath queries (CPS-1760 #2)
This fixes issues with special characters for CPS-500, CPS-1756, CPS-1758, and CPS-1760. It also improves query performance. - use SQL LIKE instead of regex in Cps Path queries Issue-ID: CPS-1763 Signed-off-by: danielhanrahan <daniel.hanrahan@est.tech> Change-Id: I5c179882bfba71d3b009c60059e9073f46227e7d
