Having ID and Secret in clear inside configuration files for static
clients is not ideal. This commit allows setting these from environment
variables.

The default cipher suites used by Go include a number of ciphers that
have known weaknesses. In addition to leaving users open to these
weaknesses, the inclusion of these weaker ciphers causes problems with
various automated scanning tools.
This PR disables the CBC-mode, RC4, and 3DES ciphers included in the
Go standard library by passing an explicit cipher suite list.
The ciphers included here are more line with those recommended by
Mozilla for "Intermediate" compatibility. [0]
*Performance Implications*
The Go standard library does capability-based cipher ordering,
preferring AES ciphers if the underlying hardware has AES specific
instructions. [1] Since all of the relevant code is internal modules,
to do the same thing ourselves would require duplicating that
code. Here, I've placed AES based ciphers first.
*Compatibility Implications*
This does reduce the number of clients who will be able to communicate
with dex.

Some environments are subject to strict rules about the permitted TLS
protocol verion and available ciphers. Setting TLSv1.2 as the minimum
version ensures we do not use weaker protocols. We've opted against
making this configurable given the age of TLSv1.2 and the increasing
push to deprecate TLSv1.1 and older.
The PreferServerCipherSuites setting is also commonly flagged by SSL
quality scanning tools. Since Go provides a relatively modern set of
default ciphers by default, defaulting this to true is unlikely to
make much practical difference.

- adapted TestUnmarshalConfig to ensure the fields are read in
- added a test to see that at least MaxOpenConns works:
- this is only exposed through (*db).Stats() in go 1.11, so this test
has a build tag
- the other two configurables can't be read back, so we've got to
trust that the mechanism works given the one instance that's tested..

This patch adds etcd storage implementation. This should be useful in
environments where
- we dont want to depends on a separate, hard to maintain SQL cluster
- we dont want to incur the overhead of talking to kubernetes apiservers
- kubernetes is not available yet, or if kubernetes depends on dex
to perform authentication and the operator would like to remove any
circular dependency if possible.

Change storace to storage in cmd/dex/config.go,
change userSearch to groupSearch in connector/ldap/ldap.go
