Add a configurable dont-fragment flag to sflow

[rgwilton]

Change Scope

Adding a boolean configuration setting to set the df-bit for sflow packets to a particular collector. This change is backwards compatible.

Platform Implementations

• Implementation IOS XR: We are adding support for this.
• I couldn't see a second implementation that implements this, most relying on setting the max packet size, but it seems a reasonable and useful addition.
