[pgAdmin4] [PATCH] History Tab rewrite in React

Hi Hackers!

*Don't panic, this patch is for AFTER 1.5 release. ;-)*

0001-Bring-React-into-the-codebase.patch is an infrastructural change. This
patch brings in the React.js library and all of the tools that are needed
for us to use React code in this project. It includes a webpack bundler to
package and minify our javascript, a js linter to help keep the javascript
code clean, and the Grunt taskrunner to manage these tasks.

0002-Creates-query-history-list.patch replaces the existing history tab
with a React-based history component. The current patch brings us to
feature-parity with the current application. However, we plan on continuing
work on the History tab as we discussed. This is the smallest digestible
chunk of work that we could send as a committable patch *after 1.5 is cut*.

*Next Steps for History Tab*
We are continuing to improve the user experience of the history tab. We
have a series of stories lined up that lead us towards a further redesigned
history tab. As we add the right hand panel and each query metadata item to
it, we will be removing each query metadata item from the list view
accordingly.

Here is the design from one of the later stories:
