Allow schema renaming for internal state tables

**Problem**
We have a logic app with SQL trigger and a function with a SQL trigger running against the same database. Both use the internal state tables. The problem is that they seem to be having different requirements regarding the schema. The SQL trigger on the function adds a not nullable LastAccessTime column which is not used by the SQL trigger on the logic app, making it fail. We now manually changed the column to be nullable. However that's not something that you'd want to do.

**Solution**
A solution to this problem would be to allow for a configurable schema name on the SQL trigger for functions.

**Describe alternatives you've considered**
We mitigated the problem by making the LastAccessTime column nullable.

Start by tracing how the SQL trigger creates and accesses its internal state tables, then compare the schema expectations of function and logic app triggers. Done means the function SQL trigger accepts a configurable schema name and avoids the conflicting LastAccessTime requirement described in the issue.
