wallet tracing POC

feature: use clap derive for nym-api + use stricter validation for other binaries (#2772 )
* fixed all uses of deprecated clap methods * updated all uses of clap to 4.0 * unified obtaining build information * moved around the imports * Moved all nym-api arguments to ApiArgs and simplified parsing * Using common shutdown signal code * Using clap for parsing Vec<Url> * stricter validation of socks5-client arguments * ibid for the native client * ibid for the gateway * ibid for the mixnode * clippy

 ## [v1.1.4] (2022-12-20)

-This release adds multiple Single Use Reply Blocks (SURBs) to allow arbitrarily-sized anonymized replies. 
-At the moment this is turned off by default, but available for use by application developers. 
-We will need to wait for network-requesters to upgrade to this new release, after which multi-SURB anonymization will become the default setting for the SOCKS proxy clients.
