* get rid of subshell + exec
The new way of executing `sha512sum` should work as well as the old way
but without the clutter and possible problems the usage of subshells +
exec incurs.
Moreover, there was a misconception about array expansion. Using `""`
around an expanding array (`${ARRAY[@]}`) is quite fine (and actually
the preffered way), not because it makes the expansion _one_ string
(this would be `${ARRAY[*]}`), but it makes sure when elements are
expanded, each element has `""` around them so to speak, i.e. there is
no re-splitting of these elements.
* removed old concerns in comments
* increase test and check for changes sleep duration
The `DYNAMIC_FILES` var was quote wrapped, treating all filepaths to create checksums for as a single string that would be ignored instead of processed individually.
Removed the quotes, and changed the for loop to an array which accomplishes the same goal.
* fix: Prevent unnecessary change detection event
`acme.json` change would extract new cert files, which would then be hashed after restarting services and considered a change event, running through the logic again and restarting services once more when that was not required.
The checksum entries for those cert files are now replaced with new entries containing updated checksum hashes, after `acme.json` extraction.
Removes duplicate logic from `check-for-changes.sh` that is used/maintained elsewhere to avoid risk of problems, as this code is already starting to diverge / rot.
---
Previously the change detection support has had code added for rebuilding config upon change detection which is the same as code run during startup scripts. Unfortunately over time this has fallen out of sync. Mostly the startup scripts would get maintenance and the contributor and reviewers may not have been aware of the duplicate code handled by `check-for-changes.sh`.
That code was starting to diverge in addition to some changes in structure (_eg: relay host logic seems interleaved here vs separated out in startup scripts_). I wanted to address this before it risks becoming a much bigger headache.
Rather than bloat `helper-functions.sh` further, I've added a `helpers/` folder extracting relevant common logic between startup scripts and `changedetector`. If you want to follow that process I've kept scoped commits to make those diffs easier. Some minor changes/improvements were added but nothing significant.

- chore: Extract relay host logic to new `relay.sh` helper
- chore: Extract `/etc/postfix/sasl_passwd` logic to new `sasl.sh` helper
- chore: Extract `postfix-accounts.cf` logic to new `accounts.sh` helper
- chore: Extract `/etc/aliases` logic to new `aliases.sh` helper
- chore: Extract `/etc/postfix/vhost` logic to new `postfix.sh` helper
- chore: Add inline docs for Postfix configs

`accounts.sh`:
- Add note regarding potential bug for bare domain setups with `/etc/postfix/vhost` and `mydestination` sharing same domain value.
`relay.sh`:
- Remove the tabs for a single space delimiter, revised associated comment.
- Add PR reference for original `_populate_relayhost_map` implementation which has some useful details.

Split into scoped commits with messages if further details are needed, view those via the associated PR :)
**Commit Summary:**
**`check-for-changes.sh`**
- Prevent `SSL_DOMAIN` silently skipping when value has wildcard prefix `*.` (_at least this was known as a bugfix when originally committed in linked PR_).
- Improved inlined docs for maintainers.
- Additional logging for debugging.
**`helper-functions.sh:_extract_certs_from_acme`**:
- Fail if the input arg (_`$CERT_DOMAIN`, aka the FQDN_) provided for extraction is empty.
- Use `$CERT_DOMAIN` in place of `$HOSTNAME` and `$1` for a consistent value (_previously could mismatch, eg with `SSL_DOMAIN` defined_).
- The conditional is now only for handling extraction failure (_key or cert value is missing from extraction_).
- Log an actual warning or success (debug) based on outcome.
- Don't use `SSL_DOMAIN` with wildcard value for the `mkdir` letsencrypt directory name (_wildcard prefix `*.` is first stripped instead_).
**`acme_extract`** (_new python utility for `acme.json` handling_):
- Extracted out into a python script that can be treated as a utility in the `$PATH` like other helper scripts. It can now be used and optionally tested directly instead of via `helper-functions.sh`.
-Made compatible with Python 3, as Python 2 is EOL and no longer in newer versions of Debian.
* changed the locking function to better support multiple servers running at once and sharing the same config
* helper function testing now runs inside of container

Centralize the collection of the HOSTNAME and DOMAINAME so that it's predictable and uniform across the various scripts (using the helper). Ensure it supports the various configurations users can have (both subdomain and without subdomain, override and no override).
---
* using _obtain_hostname_and_domainname helper + covers when not a subdomain
doc: OVERRIDE_HOSTNAME takes priority
* added tests for non-subdomain hostname + further improvements
* moved SRS DOMAINANME tests into hostname test file + Allowing DOMAINNAME ENV to override what would be automatically set
