copercini 51a4432ca8 HTTPClient Port (#347)
* Fix possible infinite loop in the example

* Remove workaround of sockets always return -76 

Remove workaround of sockets always return -76 (because it's fixed on IDF now)
Remove delay during handshake (improving stability)

* Remove unusable mbedtls_net of context creation

* Fix bad destructor

* Compatibility with WiFiClient for HTTPClient

* Initial port from ESP8266

Changed SHA1 fingerprint by Root CA verification
Changed log system

* Remove deprecated function
