Adding optional role_name parameter

[OfirYaron]

When using two clusters with the same name on two different regions under the same account, the load balancer controller ingress role is shared and being updated from both ends causing issues.

the solution was fairly simple - add an override attribute to the module: 'role_name'

• the fix is backward compatible
• if omitted the same-already-active naming convention will be used
• I've Hoisted the role name into a local with a condition and used that local in two placed it was required (easier to maintain)
