clang-tidy: Enable a clang-analyzer and readability check

This commit enables clang-analyzer-deadcode.DeadStores check
which indicates that there are variables in your code that are
assigned values but are never used beyond that assignment.
The readability-static-accessed-through-instance check verifies
when a static member of a class is accessed through an instance
of that class rather than through the class itself.

But here this check is capturing an error on "serviceName"
even when the member is a constant and not a static member.
So just ignoring this check in the function.
