rpcserver: Disable getblocktemplate.

[davecgh]

This disables the getblocktemplate RPC handler since it does not at all work as intended. Fixing it is going to be a larger effort, so just disable it until it can be properly implemented.

OK as getblocktemplate is not ready.

[crackfoo]

well, shouldn't you spend the time to fix this?

[davecgh]

@crackfoo: Of course. The description says exactly that!

Fixing it is going to be a larger effort, so just disable it until it can be properly implemented.

Also, it is important to note that Decred miners use getwork anyways because it is the preferred method in Decred. Unlike other coins, Decred provides additional space in the header itself which negates the primary reason getwork was deprecated to begin with, which is that it was unable to serve work quickly enough to fast miners.

Also, miners are able to start solving the blocks more quickly with getwork in Decred over getblocktemplate too since it's less data across the wire, which means more profit for them.

@davecgh when it will be fixing ?

We're implementing the decred POW pool by getblocktemplate.
Do you have any idea ? Many thanks:)

[detailyang]

never mind, we got it by getwork:)
