Bitcoind without docker

[k9ert]

This contains some improvements, some of them necessary for better cypress-testing:

• You can now run bitcoind without docker (--nodocker) if you have bitcoind on the PATH somewhere
• If you want the process to be quiet, run it with --quiet
• adjust the mining period, so --mining-period 0.5 will mine a block every half a second
• --datadir can now be specified and the default is /tmp/bitcoind_plain_datadir. We no longer create new temp-directories
• A CTRL-C will now always terminate the process/container. In The case of docker, the datadir will be lost as well. In the case of a plain bitcoind, we now have -reset`
• --reset remove the datadir
• the blockheight is now printed in the output
• All options are now properly documented

Here is an example-output:

Looks good! Though reset doesn't work for me, I get:

python3 -m cryptoadvance.specter bitcoind --reset --nodocker                  
Initializing HWI...
    --> Killing bitcoind-process with id 20807 ...

Yeah, that wasn't quite platform-independent. Should be better now?!

[ben-kaufman]

Works now :) I see it always starts from block 200 after reset, is that intended?

Partially. I would have expected 100. If you restart it, all wallets in .specterd get funded with a coinbase-transaction automatically. In order to be able to spend it immediately, i'm mining 100 more blocks. Makes sense?

I can have a look whether i can reduce that to 100.

Ok yes makes sense, looks good to me then
