also going back to using the engine include for a while, for some testing.

Create a new hidden provision-install-backend command, that we call during provision-install, so we can isolate php errors and recover from them. should also help with OOM errors.

This is needed so that the null service type can replace any of the real service types. So you can choose not to use any service implementation for certain things.

This reverts commit ab3b6a979fd91a79c303ffe23eb2661c6257b2cf.

Hostmaster install and migrate now makes use of the makefile flag to fetch the profile, so hostmaster-make cmd goes away.

when a platform root is no longer found, check if it has an associated makefile and fetch automatically. #373062

If the master server -> aegir_root db connection is happening on the local server, use 'localhost' as the host name.
all the grants will still happen using the remote_host of the server.

Replace the @server_localhost with @server_master, which now has the ability to have a remote_host other than localhost.

Moved the environment hiding logic to the config files process method, and have the http service OPT IN to use the cloaking.

Apache server config, and all apache syncing, always needs to use the real server. Everything else uses cluster via context.

Migration between servers works. It now deletes the vhost file first, and if it gets recreated that's cool.
