cephadm: convert all deploy tests to use funkypatch fixture
During the refactor of various daemon type classes some of the tests had
been converted to funkypatch in order to deal with imports occuring over
multiple files. However, this conversion was done piece by piece in
order to make clear what was changing. This left the functions in this
file inconsistent. Change all the remaining function to use funkypatch
for consistency.
