Allow customizing CLI locations (#225)
* Allow passing in binary source Also change destinationDir to allow a null to make it easier to pass in a setting that could be unset. * Add settings page for CLI locations * Remove unused message * Propagate non-zero exit code as exceptions Otherwise they will not be visible to the user. This is particularly important as it will probably be easy for a user to make a typo when overriding the binary URL and hit something that gives a 200 but is not actually the binary. * Load workspaces after downloading CLI Since you cannot interact with the list without a CLI (and there is now a higher chance something can go wrong since the user can customize the source and destination) we should avoid showing them until the CLI is good to go. * Check that CLI downloads the first time Getting a test failure on macOS and just want to make sure it does download the first time. * Simplify setting execute bit * Catch trying to create a directory at/under non-directory * Make CLI destination dir required
