feat: dfx start doesn't require --clean when changing replica versions or options

[ericswanson-dfinity]

Description

For the shared local network, dfx now stores replica state in a subdirectory, where the subdirectory name is a hash of the replica version and options. This means it will no longer be necessary to pass --clean when switching between dfx versions.

dfx will still reset canister ids when it detects that the local network has changed. But it will now be possible to do something like work with projects A, B, and C with dfx 0.22.0, and projects E and F with dfx 0.23.0, with dfx +0.22.0 start / dfx +0.23.0 start, without --clean, in between them.
