Update all toml dependencies to a published version

[coleFD]

We cannot publish crates that have github dependencies, and because we need no_std support, we are currently depending on a fork of the original toml repo since the published version will not compile. toml is used in all of the roles crates to deserialize the config files so we need to fix each of them.

@plebhash any updates if #812 (comment) affected this and if we can freely close it?

[plebhash]

#456 is still an unsolved issue

keeping track of this on the roles CLI standardization discussion: #857 (comment)

Removing the TOML dependency is a critical requirement for the integration test. The TOML dependency obstructs the addition of the Bitcoind crate because of its no_std constraint.

@plebhash , I'll create a separate PR to remove the TOML dependency from the roles. Could you assign the issue to me?
