Support other data storage technologies as an alternative to Raven DB

[boblangley]

There are a number of reasons why data storage technologies other than Raven DB may be desirable:

• Enterprise policy favors (perhaps exclusively) specific data storage technologies.
• Some data storage technologies are more cloud-friendly (less operational commitment, cost, performance, etc.) than others
• An in-memory data storage solution may make testing easier

Raven DB does not support networked file systems like SMB, CIFS, or NFS:

From the Raven DB docs for containers, emphasis mine:

• Non-NFS file systems are Supported.
• NTFS, Ext4, and other non-NFS volume mounts' file systems are supported.
• SMB and CIFS mounts are not supported.
• Linux Docker containers running under Windows Docker hosts via shared volumes are not supported due to CIFS protocol usage.

For on-prem container environments and non-container environments (VMs) this isn't an issue, but in the cloud networked attached storage is the norm. Cloud-friendly storage options would allow users to run SC with better integration and support in those environments.
