This change uses the updated ldap library in minio/pkg (bumped
up to v3). A new config parameter is added for LDAP configuration to
specify extra user attributes to load from the LDAP server and to store
them as additional claims for the user.
A test is added in sts_handlers.go that shows how to access the LDAP
attributes as a claim.
This is in preparation for adding SSH pubkey authentication to MinIO's SFTP
integration.

In a perf test, one node will run speed test with all nodes. If there is
an error with a peer node, the peer node name is not included in the
error hence confusing the user.
This commit will add the peer endpoint string to the netperf error.
Capture average, p50, p99, p999 response times
and ttfb values. These are needed for latency
measurements and overall understanding of our
speedtest results.
It is observed in a local 8 drive system the CPU seems to be
bottlenecked at

Bonus changes:
- re-use transport for bucket replication clients, also site replication clients.
- use 32KiB buffer for all read and writes at transport layer seems to help
TLS read connections.
- Do not have 'MaxConnsPerHost' this is problematic to be used with net/http
connection pooling 'MaxIdleConnsPerHost' is enough.
- currently subnet health check was freezing and calling
locks at multiple locations, avoid them.
- throw errors if first attempt itself fails with no results
