Version 0.21.0

This release integrates the mochi-plumber capability (formerly a separate repo/dependency) into the Margo source tree.

This is a mechanism for Margo to resolve general transport addresses (like cxi://) into more specific ones (like cxi://cxi0 or cxi://cxi1) in order to automatically utilize multiple network cards when multiple Mochi processes execute on the same node. This mechanism is enabled by default if hwloc and libfabric are present, but for now it will only attempt to manipulate CXI (Slingshot) network addresses; all others are passed through unmodified.

• make Mercury log level configurable via JSON, and adjust default values
• automatically set appropriate auth_key (if unspecified) for Slingshot networks if possible
• verbose error messages for suspected Slingshot misconfiguration scenarios

Version 0.19.0

• Added feature: spindown logic to improve performance of bursts of RPCs.

Version 0.18.1
