Add version/correlation headers to Nexus and Praxis ecosystem clients

Browse Source 
mavend's hand-rolled Nexus and Praxis HTTP clients sent bare requests
with no version or correlation headers, unlike the Hexis client.
Added a shared context-based correlation ID mechanism and version
headers (X-Nexus-Version, X-Praxis-Version) across all Nexus/Praxis
call sites, and threaded the correlation ID already generated in
executeCapability through to the Nexus/Praxis calls in the same
request chain. Synced vendor/ copy of hexis/pkg/client after its
WithCorrelationID addition.

Part of Vikunja #273.
