Environmental filter config includes:

  Kind filter:
          JVM property: `taoensso.telemere.rt-kind-filter.edn`
          Env variable: `TAOENSSO_TELEMERE_RT_KIND_FILTER_EDN`
    Classpath resource: `taoensso.telemere.rt-kind-filter.edn`

  Namespace filter:
          JVM property: `taoensso.telemere.rt-ns-filter.edn`
          Env variable: `TAOENSSO_TELEMERE_RT_NS_FILTER_EDN`
    Classpath resource: `taoensso.telemere.rt-ns-filter.edn`

  Id filter:
          JVM property: `taoensso.telemere.rt-id-filter.edn`
          Env variable: `TAOENSSO_TELEMERE_RT_ID_FILTER_EDN`
    Classpath resource: `taoensso.telemere.rt-id-filter.edn`

  Minimum level:
          JVM property: `taoensso.telemere.rt-min-level.edn`
          Env variable: `TAOENSSO_TELEMERE_RT_MIN_LEVEL_EDN`
    Classpath resource: `taoensso.telemere.rt-min-level.edn`

Examples:

  `taoensso.telemere.rt-min-level.edn`       -> ":info"
  `TAOENSSO_TELEMERE_RT_NS_FILTER_EDN`       -> "{:deny \"taoensso.*\"}"
  `taoensso.telemere.rt-id-filter.cljs.edn`  -> "#{:my-id1 :my-id2}"
  `TAOENSSO_TELEMERE_RT_KIND_FILTER_CLJ_EDN` -> "nil"

Tips:

  - The above ids are for runtime filters (the most common).
    For compile-time filters, change `rt`->`ct` / `RT`->`CT`.

  - The above ids will affect both Clj AND Cljs.
    For platform-specific filters, use
      ".clj.edn"  / "_CLJ_EDN"  or
      ".cljs.edn" / "_CLJS_EDN" suffixes instead.

  - ".edn" / "_EDN" suffixes are optional.

  - Config values should be edn. To get the right syntax, first set
    your runtime filters using the standard utils (`set-min-level!`,
    etc.). Then call `get-filters` and serialize the relevant parts
    to edn with `pr-str`.

  - All environmental config uses `get-env` underneath.
    See the `get-env` docstring for more/advanced details.

  - Classpath resources are files accessible on your project's
    classpath. This usually includes files in your project's
    `resources/` dir.
