Igor Postelnik 39065377b5 TUN-4063: Cleanup dependencies between packages.
- Move packages the provide generic functionality (such as config) from `cmd` subtree to top level.
- Remove all dependencies on `cmd` subtree from top level packages.
- Consolidate all code dealing with token generation and transfer to a single cohesive package.

Add max upstream connections dns-proxy option ()
* Add max upstream connections dns-proxy option

Allows defining a limit to the number of connections that can be
established with the upstream DNS host.

If left unset, there may be situations where connections fail to
establish, which causes the Transport to create an influx of connections
causing upstream to throttle our requests and triggering a runaway
effect resulting in high CPU usage. See https://github.com/cloudflare/cloudflared/issues/91

* Code review with proposed changes

* Add max upstream connections flag to tunnel flags

* Reduce DNS proxy max upstream connections default value

Reduce the default value of maximum upstream connections on the DNS
proxy to guarantee it works on single-core and other low-end hardware.
Further testing could allow for a safe increase of this value.

* Update dns-proxy flag name

Also remove `MaxUpstreamConnsFlag` const as it's no longer referenced in more than one place and to make things more consistent with how the other flags are referenced.

Nuno Diegues 7c3ceeeaef TUN-3757: Fix legacy Uint flags that are incorrectly handled by ufarve library
The following UInt flags:
 * Uint64 - heartbeat-count, compression-quality
 * Uint - retries, port, proxy-port

were not being correctly picked from the configuration YAML
since the multi origin refactor

This is due to a limitation of the ufarve library, which we
overcome for now with handling those as Int flags.
