OC-5645 Remove hard coded values

Remove hard coded values of username/pass/host/url from HostAccessService
Don't think this is going to work. The URL property is a concatenation of a String and host. Let's do this let's get rid of host. and have a single property with the name url. This is how the url would look like in the properties file. 

hostlist.url=

Also let's add port to the properties file
hostlist.port=
