Add transforms and domain models

* Return log events as JSON objects from API; render on front-end

Site UUID added to log events.

* Remove superfluous memoization of site UUID retrieval

Settings are already cached.

* Transfer timestamps in ISO-8601 format

* Move `metabase.metabot.instance/local-process-uuid` to `metabase.public-settings`

* Use `local-process-uuid` in stead of `site-uuid`

`site-uuid` is not unique across processes, which is what we want to
associate with log events.

* Remove unused import

* Allow log events to be filtered by process UUID on front-end

* Move process selector out of loading wrapper

Otherwise, if there are process UUIDs with no log events, the selector is
removed with the log event list.

* Figured out how to add docs to `defonce`

* Fix ns declaration

* Linter appeasement

* Merge log events received from back-end with previously received ones

This allows responses from multiple back-end instances to be spliced
together.

* Use MB components in stead of plain, styled HTML tags

The select is only displayed if more than one process UUID was found.

* Linter appeasement

* Move `metabase.public-settings/local-process-uuid` to `metabase.config`

* Fix sorting on multiple log event fields

* Flatten `Select` children to allow nested arrays of children

* Generate options directly under parent Select

* Limit the number of log events that we render

* Docstring and style updates

* Update editor config with Clojure files max line length

* Ensure that `NumericWrapper` is imported before use

* Cleanup layout

Filter out models with infinities  

* Join on collection table's ID, not the joining table's `collection_id`

This caused each record that joins on collection, to be duplicated for each
existing collection:

`LEFT JOIN collection collection ON card.collection_id = collection_id`

should be

`LEFT JOIN collection collection ON card.collection_id = collection.id`

* Test fixes from @cam on EE

* Split out inline JS from index/init templates to separate files

* Read inline JS from resources at run time

* Calculate inline JS hashes for CSP header from content

* Move inline JS to resource sub-directory

* Update and memoize inline JS loading

* Revert debug code

* Deduplicate `resp/response` calls

* Fix paths to moved inline JS resources

* Force creation of test data DB so things don't get left in the cache

This fix was provided by @camsaul.

* Combine and `defonce` inline JS hashes

* s/inlinejs/inline-js/

* Improved aggregation names for column names

* Fix tests

* Add Database auto_run_queries setting; code cleanup

* More code cleanup & test fixes

* Test fixes ?

[ci drivers]
Resolves #1851

* Test fixes 

* [segments] fix edit segments; don't use diff for definition changes

* [segments] don't use diff at all on segment updates

* [metrics] don't use diff at all on metric updates either

* [segments] use original body fields + norm'd def

* [test] wip update metric/segment tests

* [test] add simple sql humanization tests wip

* [dict][test] humanization tests to keep sql reserved words whole wip

* [humanization] wip inverse+clean dict

* [humanization] test cases

* [humanization] more user test cases

* [humanization] remove certains words from dict
