42366ba57d network: increase MOST_RELAXED default timeout to 10 minutes

e83f0dd3fc network: when switching servers, don't wait for old interface to close 
The GUI blocks until network.set_parameters returns when switching servers,
which waits for switch_to_interface, which used to wait until interface.close()
returns. interface.close() tries to flush buffered writes to the wire, with a
30 sec timeout.

If the server or the network connection is slow, flushing the buffer can take
several seconds. In particular, servers running Fulcrum always seem to
timeout in this case, freezing the GUI for 30 seconds (when switching away).

292016d283 network dialog: include protocol in server address field (#6624) 
* network-dialog: include protocol in server field

In this way it is now possible again to use plain server connections
without reverting it automatically to tls connections.

* qt network dialog: hide trailing protocol ":s" in TextEdit

This hides some complexity from casual users, while still allowing
advanced users to set the protocol.

d19ff43266 interface: check server response for some methods 
some basic sanity checks

Previously if the server sent back a malformed response, it could partially corrupt a wallet file.
(as sometimes the response would get persisted, and issues would only arise later when the values were used)

ca1046bce2 Add --serverfingerprint option (#6094) 
* Add --fingerprint option

* Simplify conditional checks

* Improve warning wording

* Throw error instead of logging and returning

* --fingerprint => --serverfingerprint

* Only run fingerprint checks against main server

* Throw error if --serverfingerprint is set for a non SSL main server

* Fix linting errors

* Don't check certificate fingerprint in a seperate connection

* Disallow CA signed certs when a fingerprint is provided

* Show clear error and then exit for Qt GUI users

* Remove leading newlines from error dialog

* Always check is_main_server() when getting fingerprint

* Document how to generate SSL cert fingerprint
