hydroflow v0.5.0

Chore

• update snapshots for previous commit
• cleanup cli quotes, loose TODO comment
• Fix string join clippy::format_collect lint
• Fix clippy::implied_bounds_in_impls from latest nightlies
• Replace or_insert_with(Vec::new) with or_default()
  Clippy lint unwrap_or_default complaining on latest nightly

New Features

• add kvs with replication example
  have both kvs_replicated and kvs, separate examples

  add flow_props_fns to cross_join (same as join), and filter

• update snapshot tests for previous two commits

• open mermaid/dot graph in browser

  • HydroflowGraph::open_mermaid() opens https://mermaid.live/

• HydroflowGraph::open_dot() opens https://dreampuf.github.io/GraphvizOnline/

Bug Fixes

• restore in-subgraph rendering of self-handoffs
• fix example kvs/kvs_replicated tests, improve comments
• surface python snapshot tests
• clippy warning on multiline string in hydro_cli, py_udf
• fix demux error messages and add tests
• Clean up degenerate subgraph error message for consistency
  Makes the pinned and latest nightly version have the same stderr output
  for consistent testing.
• Make deadlock detector filter out spruious UDP ConnectionResets on Windows
• Ignore PermissionDenied on already-closed socket on Windows
• add context.current_tick_start() without breaking the scheduler this time
• add context.current_tick_start()
• separate internal compiler operators in docs name/category/sort order

Refactor

• kvs_bench graphwrite
• cleanup kvs example more
  Add persist flow_prop_fn
• cleanup kvs example with lattice properties
  Open graphs when --graph is specified
• refactor kvs example, cleanup, use demux_enum
• update chat example to use demux_enum
• demux_enum requires enum type name, add better error handling

Test

• record snapshots for surface_scheduling.rs
• Add flow prop tests

New Features (BREAKING)

• Simplify graph printing code, add delta/cumul green edges, allow hiding of vars/subgraphs
