This will help to determine how many grpc calls are made to the
satellite.
Also remove the grpc funcs that have been added to upstream.

This moves grpc related tlsopts methods to private/grpctlsopts.
This allows to remove grpc dependency from tlsopts.

Now that we are trying to identify the root cause of the satellite load limitations (i.e. currently the satellite has a max ability of 400 rps for uploads and we need this to be higher), we are using the golang diagnostic tools to collect insight into what the bottlenecks are. We currently have a debug endpoint to gather some cpu and mem data, but it could be useful to have continuous profiling. GCP stackdriver has support for continuous profiling so lets set that up and see if it is helpful to gather more data.
This PR adds support for [GCP continuous profiler](https://cloud.google.com/profiler) which allows enabling continuous cpu/mem profiling and the stats are sent to stackdriver in google cloud console.
To enable the continuous profiling for a storj component, do the following:
- prereq: the workload must be running in GKE and have Stackdriver Profiling IAM role permissions
- provide the config flag `debug.profilename` in the config.yaml file for the workload (i.e. satellite api process, etc). The profilename should be the workload name, for example "satellite-api".
- once the above config flag is provided, the profiler will be initialized and profiling stats will automatically be sent to GCP project where the workload is running and viewable in the Stackdriver Profile page in the console
The current implementation assumes the workload is running in GKE, however if we find if useful we can add support to enable this from anywhere. But for simplicity, its configured this way assuming the main goal is to enable in production systems.

this commit updates our monkit dependency to the v3 version where
it outputs in an influx style. this makes discovery much easier
as many tools are built to look at it this way.
graphite and rothko will suffer some due to no longer being a tree
based on dots. hopefully time will exist to update rothko to
index based on the new metric format.
it adds an influx output for the statreceiver so that we can
write to influxdb v1 or v2 directly.

Currently this adds controlling of cycles.

By separating Server it allows Peers to directly embed the server
and provide customizations and hooks into rest of the services.

Multiple time.Now calls in a short amount of time
may return the exact same time.
This adds a time.Sleep() to ensure we get different internal
timing.

We want to make using uplink as easy as possible. That's why we wan't to
avoid requiring setup or import command before normal usage if user
specified --access flag. If this flag is set then rest flags should be
set as defaults.

Go will, by default, set tcp keep alives on sockets. But
the kernel does not send keep alives to sockets that have
a non-empty send queue. That can cause connections that
hang forever.
So we set TCP_USER_TIMEOUT on all of the sockets as well.
That option will close any connection that has not received
an ack for any sent data (keep alive or otherwise) in the
configured time period. This places an upper bound on the
amount of time a socket can be stuck due to a client not
acknowleding data.
See https://blog.cloudflare.com/when-tcp-sockets-refuse-to-die/
for more information on what these options do and how they
interact.
Additionally, make sure that we close every connection coming
from the listeners by wrapping them in a type with a finalizer
that closes the connection, much like the os package does for
file handles. It monitors if a connection was closed due to a
finalizer so that we can go and look for the bug if we ever
see a non-zero value.

The test case wasn't testing all the combinations.
But, testing all 3 byte combinations would take too long,
instead test special values and +- 1 of them, with some
additional noise characters.

Move rpc test that uses testplanet into private/testplanet.
This ensures that rpc doesn't have the whole system as a dependency
making it easier to separate.
This unfortunately leaves pkg/rpc without specific tests, but
we would need to write new tests that only use the core packages.
