A few of the unexported functions in agent/cache took a large number of
arguments. These arguments were effectively overrides for values that
were provided in RequestInfo.
By using a struct we can not only reduce the number of arguments, but
also simplify the logic by removing the need for overrides.
Previously the SupportsBlocking option was specified by a method on the
type, and all the other options were specified from RegisterOptions.
This change moves RegisterOptions to a method on the type, and moves
SupportsBlocking into the options struct.
Currently there are only 2 cache-types. So all cache-types can implement
this method by embedding a struct with those predefined values. In the
future if a cache type needs to be registered more than once with different
options it can remove the embedded type and implement the method in a way
that allows for paramaterization.
* Implements a simple, tcp ingress gateway workflow
This adds a new type of gateway for allowing Ingress traffic into Connect from external services.

There was an RSA private key used for testing included in the old
version. This commit updates it to a version that does not include the
key so that the key is not detected by tools which scan the Consul
binary for private keys.

The Init method provided the same functionality as the New constructor.
The constructor is both more widely used, and more idiomatic, so remove
the Init method.
This change is in preparation for fixing printing of these IDs.
This commit includes 2 things:
1. Sometimes (seemingly due to client caching), performance entries
aren't available, even for the currently executing script. This waits
until the first retrieval of 'CONSUL_HTTP_PROTOCOL' before using the
performance entries to decide this. This means that the entries aren't
inspected until ember has initialized, which means that the entries are
always available.
2. getCurrentResource/getResourceFor could potentially return undefined
if the correct entry could not be found. This adds a default {} return
value if the resource cannot be found. This means that if for whatever
reason the correct resource cannot be found at least we don't fail with
an error and just drop back to HTTP/1 functionality.
Also reduce the log level of some version checking messages on the server as they can be pretty noisy during upgrades and really are more for debugging purposes.
* Add support for ingress-gateway in CLI command
- Supports -register command
- Creates a static Envoy listener that exposes only the /ready API so
that we can register a TCP healthcheck against the ingress gateway
itself
- Updates ServiceAddressValue.String() to be more in line with Value()
* docs: Link to compatibility matrix for imageEnvoy
Added a link to the Envoy supported version in the documentation for `imageEnvoy` parameter.
* Update website/source/docs/platform/k8s/helm.html.md
This should very slightly reduce the amount of memory required to store each item in
the cache.
It will also enable setting different TTLs based on the type of result. For example
we may want to use a shorter TTL when the result indicates the resource does not exist,
as storing these types of records could easily lead to a DOS caused by
OOM.
These two notify functions are very similar. There appear to be just
enough differences that trying to parameterize the differences may not
improve things.
For now, reduce some of the cosmetic differences so that the material
differences are more obvious.
Use named returned so that the caller has a better idea of what these
bools mean.
Return early to reduce the scope, and make it more obvious what values
are returned in which cases. Also reduces the number of conditional
expressions in each case.
The envoy version was updated after the PR which added this test was opened, and
merged before the test was merged, so it ended up with the wrong version.
The test had two racy bugs related to memdb references.
The first was when we initially populated data and retained the FederationState objects in a slice. Due to how the `inmemCodec` works these were actually the identical objects passed into memdb.
The second was that the `checkSame` assertion function was reading from memdb and setting the RaftIndexes to zeros to aid in equality checks. This was mutating the contents of memdb which is a no-no.
With this fix, the command:
```
i=0; while /usr/local/bin/go test -count=1 -timeout 30s github.com/hashicorp/consul/agent/consul -run '^(TestReplication_FederationStates)$'; do i=$((i + 1)); printf "$i "; done
```
That used to break on my machine in less than 20 runs is now running 150+ times without any issue.

On recent Mac OS versions, the ulimit defaults to 256 by default, but many
systems (eg: some Linux distributions) often limit this value to 1024.
On validation of configuration, Consul now validates that the number of
allowed files descriptors is bigger than http_max_conns_per_client.
This make some unit tests failing on Mac OS.
Use a less important value in unit test, so tests runs well by default
on Mac OS without need for tuning the OS.
The api client should never rever to HTTP if the user explicitly
requested TLS. This change broke some tests because the tests always use
an non-TLS http server, but some tests explicitly enable TLS.
The new grpcAddress function contains all of the logic to translate the
command line options into the values used in the template.
The new type has two advantages.
1. It introduces a logical grouping of values in the BootstrapTplArgs
struct which is exceptionally large. This grouping makes the struct
easier to understand because each set of nested values can be seen
as a single entity.
2. It gives us a reasonable return value for this new function.
