[#4813] Remove dead code from puppet/rails/host.rb

def self.clean – became orphaned in commit 28cee40689440388994a4768bd301ae32c8ecc05

def self.store – became orphaned in commit 863c50b1273a7fa48d74fb74948938214b45967c

def fact – was added as a helper method for unit tests in commit
9f4870637ce57d548d23c0b3330200014327c268. The test file that used this
method was removed in commit 93246c0c70796a606fc8c05b51e1feb09c94e377

def update_connect_time – Not sure when this was ever used.

I also ran a client master storeconfigs run a few times and didn’t see
any problems, so I’m pretty sure deleting these methods is safe.
