* Fix handling of username_as_alias during LDAP authentication
There is a bug that was introduced in the LDAP authentication method by https://github.com/hashicorp/vault/pull/11000.
It was thought to be backward compatible but has broken a number of users. Later
a new parameter `username_as_alias` was introduced in https://github.com/hashicorp/vault/pull/14324
to make it possible for operators to restore the previous behavior.
The way it is currently working is not completely backward compatible thought
because when username_as_alias is set, a call to GetUserAliasAttributeValue() will
first be made, then this value is completely discarded in pathLogin() and replaced
by the username as expected.
This is an issue because it makes useless calls to the LDAP server and will break
backward compatibility if one of the constraints in GetUserAliasAttributeValue()
is not respected, even though the resulting value will be discarded anyway.
In order to maintain backward compatibility here we have to only call
GetUserAliasAttributeValue() if necessary.
Since this change of behavior was introduced in 1.9, this fix will need to be
backported to the 1.9, 1.10 and 1.11 branches.

A change in copystructure has caused some panics due to the custom copy
function. I'm more nervous about production panics than I am about
keeping some bad code wiping out some existing warnings, so remove the
custom copy function and just allow direct setting of Warnings.
--------------------------
Added new configuration option to ldap auth backend - groupfilter.
GroupFilter accepts a Go template which will be used in conjunction with
GroupDN for finding the groups a user is a member of. The template will
be provided with context consisting of UserDN and Username.
Simplified group membership lookup significantly to support multiple use-cases:
* Enumerating groups via memberOf attribute on user object
* Previous default behavior of querying groups based on member/memberUid/uniqueMember attributes
* Custom queries to support nested groups in AD via LDAP_MATCHING_RULE_IN_CHAIN matchind rule
There is now a new configuration option - groupattr - which specifies
how to resolve group membership from the objects returned by the primary groupfilter query.
Additional changes:
* Clarify documentation for LDAP auth backend.
* Reworked how default values are set, added tests
* Removed Dial from LDAP config read. Network should not affect configuration.
This introduces a function that compares two string policy sets while
ignoring the presence of "default" (since it's added by core, not the
backend), and ensuring that ordering and/or duplication are not failure
conditions.
Fixes#1256
