William Banfield bc2b529b95 inspect: add inspect mode for debugging crashed tendermint node (#6785)
EDIT: Updated, see [comment below]( https://github.com/tendermint/tendermint/pull/6785#issuecomment-897793175)

This change adds a sketch of the `Debug` mode. 

This change adds a `Debug` struct to the node package. This `Debug` struct is intended to be created and started by a command in the `cmd` directory. The `Debug` struct runs the RPC server on the data directories: both the state store and the block store.

This change required a good deal of refactoring. Namely, a new `rpc.go` file was added to the `node` package. This file encapsulates functions for starting RPC servers used by nodes. A potential additional change is to further factor this code into shared code _in_ the `rpc` package. 

Minor API tweaks were also made that seemed appropriate such as the mechanism for fetching routes from the `rpc/core` package.

Additional work is required to register the `Debug` service as a command in the `cmd` directory but I am looking for feedback on if this direction seems appropriate before diving much further.

Tendermint RPC

Pagination

Requests that return multiple items will be paginated to 30 items by default. You can specify further pages with the ?page parameter. You can also set a custom page size up to 100 with the ?per_page parameter.

Subscribing to events

The user can subscribe to events emitted by Tendermint, using /subscribe. If the maximum number of clients is reached or the client has too many subscriptions, an error will be returned. The subscription timeout is 5 sec. Each subscription has a buffer to accommodate short bursts of events or some slowness in clients. If the buffer gets full, the subscription will be canceled ("client is not pulling messages fast enough"). If Tendermint exits, all subscriptions are canceled ("Tendermint exited"). The user can unsubscribe using either /unsubscribe or /unsubscribe_all.
