Nick Khyl	2336c340c4	util/syspolicy: implement a syspolicy store that reads settings from environment variables ... In this PR, we implement (but do not use yet, pending #13727 review) a syspolicy/source.Store that reads policy settings from environment variables. It converts a CamelCase setting.Key, such as AuthKey or ExitNodeID, to a SCREAMING_SNAKE_CASE, TS_-prefixed environment variable name, such as TS_AUTH_KEY and TS_EXIT_NODE_ID. It then looks up the variable and attempts to parse it according to the expected value type. If the environment variable is not set, the policy setting is considered not configured in this store (the syspolicy package will still read it from other sources). Similarly, if the environment variable has an invalid value for the setting type, it won't be used (though the reported/logged error will differ).
