* added weighted round robin algorithm to load balancer
* added an adapt integration test for wrr and fixed a typo
* changed args format to Caddyfile args convention
* added provisioner and validator for wrr
* simplified the code and improved doc
When only a single request has the least amount of requests, there's no need to compute a random number, because the modulo of 1 will always be 0 anyways.
* log: make `sink` encodable
* deduplicate logger fields
* extract common fields into `BaseLog` and embed it into `SinkLog`
* amend godoc on `BaseLog` and `SinkLog`
* minor style change

* added some tests for parseUpstreamDialAddress
Test 4 fails because it produces "[[::1]]:80" instead of "[::1]:80"
* support absolute windows path in unix reverse proxy address
* make IsUnixNetwork public, support +h2c and reuse it
* add new tests
* If upstreams are all using same host but with different ports
ie:
foobar:4001
foobar:4002
foobar:4003
...
Because fnv-1a has not a good enough avalanche effect
Then the hostByHashing result is not well balanced over
all upstreams
As last byte FNV input tend to affect few bits, the idea is to change
the concatenation order between the key and the upstream strings
So the upstream last byte have more impact on hash diffusion
* reverseproxy: Mask the WS close message when we're the client
* weakrand
* Bump golangci-lint version so path ignores work on Windows
* gofmt
* ugh, gofmt everything, I guess
e338648fed introduced multiple upstream
addresses. A comment notes that mixing schemes isn't supported and
therefore the first valid scheme is supposed to be used.
Fixes setting the first scheme.
fixes#5087
Ideally I'd just remove the parameter to caddy.Context.Logger(), but
this would break most Caddy plugins.
Instead, I'm making it variadic and marking it as partially deprecated.
In the future, I might completely remove the parameter once most
plugins have updated.
* feat: Multiple 'to' upstreams in reverse-proxy cmd
* Repeat --to for multiple upstreams, rather than comma-separating in a single flag

* reverseproxy: Close hijacked conns on reload/quit
We also send a Close control message to both ends of
WebSocket connections. I have tested this many times in
my dev environment with consistent success, although
the variety of scenarios was limited.
* Oops... actually call Close() this time
* CloseMessage --> closeMessage
