acme_server: fix reload of acme database (#3874)
* acme_server: Refactor database creation apart from authority creation

This is a WIP commit that doesn't really offer anything other than
setting us up for using a UsagePool to gracefully reload acme_server
configs.

* Implement UsagePool

* Remove unused context

* Fix initializing non-ACME CA

This will handle cases where a DB is not provided

* Sanitize acme db path and clean debug logs

* Move regex to package level to prevent recompiling

There have been some issues with the badger storage engine
being used by the embedded acme_server. This will replace
the storage engine with bbolt

* Switch database path back to acme_server/db and remove if directory

headers: Support default header values in Caddyfile with '?' (#3807)
* implement default values for header directive

closes #3804

* remove `set_default` header op and rely on "require" handler instead

This has the following advantages over the previous attempt:

- It does not introduce a new operation for headers, but rather nicely
  extends over an existing feature in the header handler.
- It removes the need to specify the header as "deferred" because it is
  already implicitely deferred by the use of the require handler. This
  should be less confusing to the user.

* add integration test for header directive in caddyfile

* bubble up errors when parsing caddyfile header directive

* don't export unnecessarily and don't canonicalize headers unnecessarily

* fix response headers not passed in blocks

* caddyfile: fix clash when using default header in block

Each header is now set in a separate handler so that it doesn't clash
with other headers set/added/deleted in the same block.

* caddyhttp: New idle_timeout default of 5m

* reverseproxy: fix random hangs on http/2 requests with server push (#3875)

see https://github.com/golang/go/issues/42534

* Refactor and cleanup with improvements

* More specific link

caddyhttp: Return error if error handling error
Before, if there was an error in the error handler, we would not write a
status code, which resulted in Go writing a 200 for us by default, which
does not make sense when there's an error. Now we write the second
error's status if available, otherwise 500.

basicauth: Minor internal improvements (#3861)
* nitpicks and small improvements in basicauth module

1:
roll two if statements into one, since err will be nil in the second case anyhow

2:

3:
switch cache sync.Mutex to sync.RWMutex for better concurrency on cache fast track

caddyauth: Prevent user enumeration by timing
Always follow the code path of hashing and comparing a plaintext
password even if the account is not found by the given username; this
ensures that similar CPU cycles are spent for both valid and invalid
usernames.

httpcaddyfile: Improve AP logic with OnDemand
We have users that have site blocks like *.*.tld with on-demand TLS
enabled. While *.*.tld does not qualify for a publicly-trusted cert due
to its wildcards, On-Demand TLS does not actually obtain a cert with
those wildcards, since it uses the actual hostname on the handshake.

This improves on that logic, but I am still not 100% satisfied with the
result since I think we need to also check if another site block is more
specific, like foo.example.tld, which might not have on-demand TLS
enabled, and make sure an automation policy gets created before the
more general policy with on-demand...
