Actually do per-actor-caching in `open_symcache()`

Use `dict.get()` instead of `try/except KeyError` for the actor-level
`_caches` lookup; actually store the loaded `symcache` back into
`_caches[provider]` so subsequent opens retrieve any in-mem cache
instance.

Deats,
- swap `_caches[provider]` `KeyError` catch to
  `.get()` with `if symcache:` guard.
- assign result back to `_caches[provider]` before
  yielding so the cache is persistent across calls.
- rename local `cache` -> `symcache` throughout.
- add `loglevel` param and init `get_console_log()`
  at function scope.

Also,
- improve `log.info()` msgs with `{provider!r}`,
  load-latency, and cachefile path details.
- demote "no cache exists" from `.warning()` to
  `.info()`.
- track `from_msg` to distinguish "NEW request to
  provider" vs loaded-from-file in final log line.
- reformat `or` conditions to multiline style.
- move `import time` to module-level.
