launchd for igloosync-dropbox setup with gocryptfs (macOS support)

[arcticicestudio]

Epic: #131
Related to #58

The new launchd snowblock should include a user agent defining a job to auto-mount the sync gocryptfs volume located in the Dropbox folder receiving the password stored in the macOS Keychain via the macOS builtin system CLI tool security.

It should also include a documentation to describe the requirements for the com.arcticicestudio.igloo.launchd.igloosync agent. It should contain information about dependencies and how to create the required gocryptfs password stored- and received via the macOS builtin system CLI tool security.

snowsaw core plugin configuration

clean

The target path ~/Library/LaunchAgents should be cleaned before the link core plugin execution.

link

The target paths ~/Library/LaunchAgents for all agent files should be created by snowsaw if they doesn't exist yet.

Note that this is a macOS specific snowblock and therefore the com.arcticicestudio.igloo.launchd.igloosync-dropbox.plist agent file should only be linked for the iceowl host.
