Updates inventory to IBM.infosvr v2

Renames the inventory group names to use _ rather than -, per IBM.infosvr role v2.

Note: if using this version after using a previous version, you will need to change the group names in any pre-existing inventories you've been using to match this new naming convention.

Further cleanups

Addresses remaining issues identified by Galaxy.

Cleanups

Proactive cleanups for issues identified by Galaxy.

Simplifies variable naming

Simplifies the naming of variables used to control which objects the role should maintain.

Adds lineage (flow) imports

Add the ability to load custom lineage (flow) documents: both through expected XML format of the API as well as through a YAML-based generator.

Also adds certificate verification, re-using IBM.infosvr role's retrieval of the domain tier's SSL certificate so that it works even when self-signed.

Bug fix

Fixes issue with nested assets (containment hierarchies) -- XML template was using wrong attribute name for references (value instead of assetIDs).

Removes privilege escalation and moves to local execution

Removes the need for privilege escalation (see README for pre-requisites that need to be met), and moves to executing entirely on the local control machine.

Replaces rsync and cleanups

• Replaces use of synchronize module that could be problematic due to rsync dependencies with a simple copy
• Role now cleans up after itself (ie. removes transferred files) after completion
• Cleans up Ansible output

Permissions fixes

• Ensures appropriate ownership of rsync'd bundle files
• Removes warnings about using curl (URI module in Ansible is insufficient to multi-form post binary files)
