Investigate if the http client library is closing sockets as expected

[TomasTurina]

Description

The http client library uses Boost Beast's HTTP and HTTPS sockets to execute requests.

Every time a new request is executed, a new socket is created which is used to create the communication with the server.

Additionally, sockets have a Close function which must be called at the end of the operation to properly close the socket. However, this function is not currently being used and needs to be evaluated.

Tasks

• Investigate the use of the Close socket functions and in which cases they should be called.
• If necessary, adapt the current http client code to use them.
• Be sure to test this change on all supported operating systems.
