Encode api key in header, POST request body and GET query param for
search as utf-8 to avoid the multibyte char in request issue when
making API calls from khoj.el to khoj server.
Resolves#935
Exposes a transient switch with available agents as selectable options
in the Khoj chat sub-menu.
Currently shows agent slugs instead of agent names as options. This
isn't the cleanest but gets the job done for now.
Only new conversations with a different agent can be started. Existing
conversations will continue with the original agent it was created with.
The ability to switch the conversation's agent doesn't exist on the
server yet.
