Closes#4370
* hash size should be equal to tmhash.Size
* make maxRetryAttempts uint
* make maxRetryAttempts uint16
maxRetryAttempts possible - 68 years
* we do not store trustingPeriod
* added test to create client from trusted store
* remove header and vals from primary
to make sure we're restoring them from the DB
As opposed to checking a random witness, all witnesses provided should be used as a reference against the header provided by the primary node. This increases security (at the tradeoff of speed) but also gives control to the user. The more witnesses provided, the more secure the lite client can be.
Closes#4328
When TrustedHeader(height) is called, if the height is less than the trusted height but the header is not in the trusted store then a function finds the previous lowest height with a trusted header and performs a forwards sequential verification to the header of the height that was given. If no error is found it updates the trusted store with the header and validator set for that height and can then return them to the user.
Commits:
* drafted trusted header
* created function to find previous trusted height
* updates missing headers less than the trusted height
* minor cosmetic tweaks
* incorporated suggestions
* lite2: implement Backwards verification
and add SignedHeaderAfter func to Store interface

* remove unused method
* write tests

Closes issue #4338
Uses a wrapper function around both the signedHeader and validatorSet calls to the primary provider which attempts to retrieve the information 5 times before deeming the provider unavailable and replacing the primary provider with the first alternative before trying recursively again (until all alternatives are depleted)
Employs a mutex lock for any operations involving the providers of the light client to ensure no operations occurs whilst the new primary is chosen.
Commits:
* created swapProvider function
* eliminates old primary provider after replacement. Uses a mutex when changing providers
* renamed to replaceProvider
* created wrapped functions for signed header and val set
* created test for primary provider replacement
* implemented suggested revisions
* created Witnesses() and Primary()
* modified backoffAndJitterTime
* modified backoffAndJitterTime
* changed backoff base and jitter to functional arguments
* implemented suggested changes
* removed backoff function
* changed exp function to match go version
* halved the backoff time
* removed seeding and added comments
* fixed incorrect test
* extract backoff timeout calc into a function

* lite2: add Start method
There are few reasons to do that:
1) separation of state and dynamics (some users will want to delay
starting the light client; does not matter we should not allow them
to create a light client object)
2) less important, but some users might not need autoUpdateRoutine and
removeNoLongerTrustedHeadersRoutine routines
* lite2: wait till routines are finished in Stop
because they are started in Start, it feels more natural to wait for
them to finish in Stop.
* lite2: add TrustedValidatorSet func
* refactor cleanup code
* changed restore header and val function to handle negative height
* reverted restoreTrustedHeaderAndNextVals() functionality

* lite2: advance to latest header
without any exponential steps
rename autoUpdate to autoUpdateRoutine
* lite2: wait in Cleanup until goroutines finished running
* lite2: move AutoClient into Client
Most of the users will want auto update feature, so it makes sense to
move it into the Client itself, rather than having a separate
abstraction (it makes the code cleaner, but introduces an extra thing
the user will need to learn).
Also, add `FirstTrustedHeight` func to Client to get first trusted height.

NOT 1 header at a time

Fullnode mode : fullnode mode does not have any capability to participate on consensus
Validator mode : this mode is exactly same as existing state machine behavior. sync without voting on consensus, and participate consensus when fully synced
Seed mode : lightweight seed mode only for maintain an address book, p2p like TenderSeed
