Endline census data- rename preload variables

[Archi11Gupta]

We must rename these preload variables. We can add a prefix r_ so that we know these are preload variables. There are other Cen_ variables in this dataset and it might create a conflict. I am adding a list of all preload variables that don't have the prefix r_in them

I think I added all, but let me know. I did this in "1_8_A_Endline_cleaning_v2.do" as adhoc solution since I did not want to touch Astha's code. @avohra29 (I think it make sense for you to resolve in your code)

Since these are individual-level variables we don't need them in the master-level HH dataset so when we create a master merged baseline and endline individual dataset there we can address this problem.
