This PR removes lite & renames lite2 to light throughout the repo

Signed-off-by: Marko Baricevic <marbar3778@yahoo.com>

Closes: #4944

See e.g. https://github.com/tendermint/tendermint/issues/4925#issuecomment-637929251 for people getting hit by this. Should we document it elsewhere as well?

## Description



Closes: #XXX

Closes #4801

* lite2: check header w/ witnesses only when doing bisection

Closes #4872

We don't need to check witnesses if we're doing backwards hash chain
verification. I also think we don't need to do it when sequential
verification is being used.

* lite2: require 1 witness only when verificationMode=skipping

https://github.com/tendermint/tendermint/pull/4929#pullrequestreview-423256477

we don't need witnesses when performing sequential verification (except
when primary fails)

Closes #4838

Previously, we're only setting MaxOpenConnections, whereas we should set
all config variables based on user's config.toml.

## Description

- remove keyname suffix from keys


Closes: #2228

* proto: move mempool to proto

- changes according to moving the mempool reactor to proto

Signed-off-by: Marko Baricevic <marbar3778@yahoo.com>

Closes: #2883

validation of lunatic evidence requires that the node retrieve the header at the height of the infringement from the block store for comparison

Closes #4837

- `/block_results`

  before:

  failed to update light client to 7: failed to obtain the header #7: signed header not found

  after:

  We can't return the latest block results because we won't be able to
  prove them. Return the results for the previous block instead.

- /block_results?height=X`

  no changes

Ethermint currently has to maintain a map height-> block hash on the store (see here) as it needs to expose the eth_getBlockByHash JSON-RPC query for Web3 compatibility. This query is currently not supported by the tendermint RPC client.

## Description

I was able to reproduce this non-determinism locally
After increasing the timeout to 8 seconds from 5 I was not able to reproduce it

Closes: #2856

Final step of a point release.

## Description

in consensus/state.go, when calulating metrics, retrieve address (ergo, pubkey) once prior to iterating over validatorset to ensure we do not make excessive calls to signer.

Partially closes: #4865

attempt to fix #4270

TestMempoolProgressAfterCreateEmptyBlocksInterval and other tests which
rely on ensureTimeout

Updates our development and release process to match the process outlined in #4860. 

Also elaborates on a few git/Github conventions that we've discussed in the past.

## Description

Add Timeouts to Github action jobs. The goal of adding timeouts is so if a job is hanging on something it gets killed and the author will get notified. 

I picked these times based on previous circle and Github action times then doubled & in some places tripled the times.
