ipareplica role: Remove usage of undefined parameters.

Some ipareplica role had a few module calls with parameters set like
'some_argument | default(omit)' that were not actually available in such
modules. If a user provided 'some_argument', the paramater would then
be passed to the module and ipareplica deployment would fail.

By removing the parameters from the 'install' task, ipareplica
deployment works even if the variables are set by the user.
