Config: Can add static headers to email messages (#79365)
* Can add allowed custom headers to an email Message. WIP.

* adds slug as a custom email header to all outgoing emails

* Headers are static - declared as key/value pairs in config. All static headers get added to emails.

* updates comment

* adds tests for parsing smtp static headers

* updates test to assert static headers are included when building email

* updates test to use multiple static headers

* updates test names

* fixes linting issue with error

* ignore gocyclo for loading config

* updates email headers in tests to be formatted properly

* add static headers first

* updates tests to assert that regular headers like From cant be overwritten

* ensures only the header is in a valid format for smtp and not the value

* updates comment and error message wording

* adds to docs and ini sample files

* updates smtp.static_headers docs examples formatting

* removes lines commented with semi colons

* prettier:write

* renames var
