Unfortunately, testing this code is not possible without an additional wrapper
in `input`, but adding it just to test this seems to be too excessive. Fixes
It allows to invoke native contracts as committee
from CLI in privnet, e.g. to set new oracle nodes.
Also don't require `out` flag in `multisig sign`
if tx is to be pushed.
In #1104 wallet path argument has changed from `--path` to `--wallet`
but cli application still getting wallet path with `ctx.String("path")`
instead of `ctx.String("wallet")`.
This makes rpc flags consistent across all commands, previously some commands
used 'endpoint, e' and some 'rpc, r', some had ability to change timeout and
some hadn't. Now 'rpc-endpoint, r' is used everywhere along with 'timeout, t'.
Implement ability to sign transactions with multisig address.
This should be done in several steps:
1. Create TX with `wallet transfer --out <file>`
2. Sign TX with `wallet multisign sign --in <file> --out <file2>`.
3. Repeat 2 for every party.
Input file contains transaction with possibly incomplete
set of the signatures. Output file will contain the same tx
with updated signature set.
When --rpc flag is provided, result transaction is sent
via `sendrawtransaction`.
