Search query is especially slow if a user searches a generic string
which matches many records, in such case search can take tens of
seconds or time out. To speed up the search query, we search only for
first 1000 records, if there is >1000 matching records we just display
"1000+" instead of precise total count supposing that with such amount
the exact count is not so important for the user.

Because for issues even limited search was not fast enough, 2-phase
approach is used for issues: first we use simpler/faster query to get
all public issues, if this exceeds the limit, we just return the limit.
If the amount of matching results is lower than limit, we re-run more
complex search query (which includes also confidential issues).
Re-running the complex query should be fast enough in such case because the
amount of matching issues is lower than limit.

Because exact total_count is now limited, this patch also switches to
to "prev/next" pagination.

Fix failed LDAP logins when sync_ssh_keys is included in config

Closes #4662

See merge request gitlab-org/gitlab-ee!4202

We tell users to set `sync_ssh_keys` to `false` if they don't
intend to use the feature. Strangely, `true` is not how you
enable it, rather you give it an LDAP attribute name. The
default value for `sync_ssh_keys` is `nil` which doesn't break
`Gitlab::LDAP::Person.ldap_attributes`, but `false` does. This
rejects `false` *and* `true` for good measure and adds an EE-only
test to ensure it doesn't regress.
