wolfMQTT Espressif ESP32 Managed Component Support

[gojimmypi]

Heads up I'm working on an Espressif Managed Component of wolfMQTT to be published at: https://components.espressif.com/

I'm currently developing to a staging instance at: https://components-staging.espressif.com/

I'm using my own login for staging instance - so my test component is at gojimmypi/mywolfmqtt.

See also the live wolfSSL component at https://components.espressif.com/components/wolfssl/wolfssl

and my staging wolfSSL at https://components-staging.espressif.com/components/gojimmypi/mywolfssl

WIP is located on the component-manager branch of my fork of wolfMQTT.

To publish wolfMQTT, see the INSTALL.md file.

See also: wolfSSL/wolfssl#6708 and wolfSSL/wolfssh#588 as well as wolfSSL/wolfssl#6234 for a roadmap of all Espressif improvements currently in progress.
