Description

There are some cases where it may be beneficial to use link properties (since link capabilities do not allow for key-value pairs, they can't easily convey a desired configurable value and the properties on a terminus refer to the dynamically created node not the link or the terminus itself).

(I've set this to minor since major feels a little strong, but I do think its important ultimately for the engine to expose all the extension points from the protocol.)

• blocks: DISPATCH-1745 Link routing does not propagate link properties
• is depended upon by: DISPATCH-1368 Link (address) priority is ignored by the second hop router
• is depended upon by: PROTON-2106 Make link properties available in Go
• is duplicated by: PROTON-2066 provide access to the properties map sent in the link attach performative
• relates to: PROTON-1082 add ability to specify and inspect properties for link attach frames
