Merging the UI into the web project

[ejsmith]

• Serve the SPA app files from the Web project
• Automatically start the SPA site (npm run serve) when running the web project
• Make it so that doing dotnet publish will build the ClientApp and add the files to the output
• Clean up some old dependencies like puppeteer
• Automatically use same SSL cert from the ASPNETCORE app
• Automatically pickup host, port and ssl settings from the ASPNETCORE app
• Proxy to API so requests can be run on a single domain and doesn't require CORS
• Single web docker image. Get rid of UI docker image
• Fix issue with fallback routing not working. Should serve SPA index page when a request comes in that doesn't match an endpoint
• Make it so that when BaseURL is empty, it calls back to same site
• Remove client version from bottom of UI. We will have a single version now
• Update README to explain how to work on the front end without running the back end (set API url)
• Update README to explain how to work on just the back end without running the front end (change to the Exceptionless API launch profile / remove ASPNETCORE_HOSTINGSTARTUPASSEMBLIES)
• Update k8s / prod to remove UI service and use combined Web / UI instead

Looks great, just some minor client side issues I left comments on.
