Replaced the conflicting vrf_str variable name with vrf_text throughout the code to resolve naming conflicts with the vrf_str() function.

this pr has some major problems
a) it doesn't follow our commit guidelines about how the commit message should be formated
b) the commit has multiple unrelated changes to what is described
c) Looks like a fat finger removal of a non-trivial number of lines occurred.
