FoDMessages.properties and possibly others: Remove old fcli 1.x variable references

[rsenden]

Current Behavior

For example, the following usage messages use the fcli 1.x - syntax to reference transient/session-specific variables; this syntax is no longer supported on fcli 2+:

If these usage messages are still being displayed in fcli help output, they should be updated to show the new fcli variable syntax. If these usage messages are no longer being displayed in fcli help output, they should be removed.

Potentially there are other usage messages that still show old fcli variable syntax; we should review all resource bundles and update accordingly.

Expected Behavior

• Usage messages that are no longer in use should be removed
• Usage messages that are still in use should display fcli 2.x variable syntax
