Add transforms and domain models

* revert text-medium color to #74838f

* use light instead of medium on preview button

* Factor out test for access to localStorage

This allows code that uses localStorage to test against
`window.hasLocalStorage`, in stead of handling exceptions generated when
access to localStorage is denied.

* Move check for localStorage to metabase/lib/dom

* 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

Notebook Mode + View Mode + Joins + etc

* don't strip options from filter when updating relative date values

* appease flow

* Fix flow type and don't add null options

* Add Database auto_run_queries setting; code cleanup

* More code cleanup & test fixes

* Test fixes ?

* Handle long names better

* Minor fix to dashboard title

* Forgot yarn prettier

* Revert text-wrap on SelectButton until I understand the unit test fail

* Make it work in all browsers

* flex-wrap date selector, and various other fixes to start, x-ray, data model, wrong text and missing i18n

* Fix duplicate tableMetadata

* Moved prop incorrectly

* Fix bad merge with new eslint rule

* Setting MB_JETTY_HOST in test runner (not sure this achieves anything TBH)

* Disable draggable action buttons on cards when editing dashboard

* Card filter parameter mappings should not be draggable either (5365, 7068)

* Filter mapping Prettier

* changes "null" to "nil" for embedded ruby example

* moves :exp out of the :params

* lint cleanup
