Callum Waters df3eee455c lite2: replace primary provider with alternative when unavailable (#4354)
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.
