Refactor https

[lbussy]

Probable help for #128 and #129. Still occasionally panics within HTTPClient::sendRequest() but I'm beating on it pretty hard (four sheets every 10 seconds.)

Removes SecureWithRedirects completely since HTTPClient::setFollowRedirects() is now a thing.

Have also moved back to the regular WiFiManager and AsyncWebServer since they seem to now work well together.

Additionally, I have removed the DHCP hack since that kills the stack with the current arduino-esp32 packages.

The crash I am getting seems to be upstream in HTTPClient::~HTTPClient():

Rebooting...

Someone posted what they think fixes it here but I'm not sure if it happens enough to hack the arduino-esp32 code.
