* Renaming all instances of nymd to nyxd * Might as well get the changelogs too * Making it clearer that an ApiClient is a NymApiClient * Lining up config templates with struct keys on gateway * Changed the last references to validator_urls to nyxd_urls * Fixed up a few type errors after refactoring * Changed the changelog * Fixed typo in changelog * Further instances of renaming 'nymd' + introducing additional clap aliases * updated environmental variables and allowed usage of deprecated variants * missing occurences of coconut-locked environmental variables Co-authored-by: Jędrzej Stuczyński <jedrzej.stuczynski@gmail.com>
