feat(wireguard): add standalone wireguard (#3575)

* feat(wireguard): add standalone wireguard

* hmm

* try

* empty space

* configmap

* formatting

* mount

* full priv for testing

* lint

* see files

* lint

* actually mount it

* see content

* allow native helm users to pass conf file directly and update UI

* test secret mount

* disable /tmp

* default mode

* hmm

* lets see

* defaultMdoe

* root for testing

* configfilehostpath is required for scale

* fix def mode

* string

* render secret

* quote

* first encode then ident

* octal

* try hostpath

* rootless test

* fake config

* test normal run

* root

* rofs

* fake key

* fake key

* add keys for ci

* remvoe ci values
