In my ever-growing list of test failures, I was seeing this one intermittently.
```
Running 2nd level testscript pruning.py...
Initializing test directory /tmp/testY5ypCv
Warning! This test requires 4GB of disk space and takes over 30 mins (up to 2 hours)
Mining a big blockchain of 995 blocks

Failed
```
After digging into the test, I found that the code is waiting 10 seconds for blk00000.dat to be deleted, and then throwing this failure if it still exists after 10 seconds.
I increased this amount, had the script print the actual time taken, and ran the test a few more times. The time taken ranged between 8 to 12 seconds. So, I feel that this timeout is too short.
After changing the timeout to 30 seconds, the test passes consistently.

We can't change "softforks", but it seems far more logical to use tags
in an object rather than using an "id" field in an array.
For example, to get the csv status before, you need to iterate the
array to find the entry with 'id' field equal to "csv":
jq '.bip9_softforks | map(select(.id == "csv"))[] | .status'
Now:
jq '.bip9_softforks.csv.status'
There is no issue with fork names being incompatible with JSON tags,
since we're selecting them ourselves.

Check the Content-Type header that is returned from the RPC server. Only
if it is `application/json` the data is supposed to be parsed as JSON.
This gives better reporting if the HTTP server happens to return an error that is
not JSON-formatted, which is the case if it happens at a lower level
before JSON-RPC kicks in.
Before: `Unexpected exception caught during testing: No JSON object could be decoded`
After: `JSONRPC error: non-JSON HTTP response with '403 Forbidden' from server`
Avoid an infinite loop in encoding, by ensuring EncodeDecimal
returns a string. round(Decimal) used to convert it to
float, but it no longer does in python 3.x. Strings are
supported since #6380, so just use that.
Replace the `bitcoin-cli -rpcwait` after spawning bitcoind
with our own loop that detects when bitcoind exits prematurely.
And if one node fails to start, stop the others.
This prevents a hang in such a case (see #7463).
Adds two RPC tests for the generatetoaddress RPC, one in the wallet, and one when the wallet is disabled.
The wallet RPC Test mines Bitcoin to another node's address and checks that that node has received the Bitcoin.
The RPC test without the wallet mines Bitcoin to an arbitrary address and checks that it works. It then mines to an arbitrary invalid address and checks that that fails.
This RPC test will test both the activation mechanism of the first versionbits soft fork as well as testing many code branches of the consensus logic for BIP's 68, 112, and 113.
