Allow /local/path for *_URL parameters within config file

[ryanRfox]

Problem

As a dev I may frequently modify go-algorand or indexer code on my local file system. I don't want to push to GitHub each change prior to testing the build using sandbox. Currently, supplying /path/to/my/repo for ALGOD_URL field within my.config configuration file results in the error "fatal: /path/to/my/repo does not exist". I'll make the assumption the INDEXER_URL behaves similarly.

Solution

Proposed by @joe-p:

1. Comment out this line: https://github.com/algorand/sandbox/blob/ef26221e9eb7141482234d061950e8a807f07a0c/images/algod/install.sh#L61

git clone --single-branch --branch "${BRANCH}" "${URL}"

2. Then add a COPY command similar to this line that copies in the repo to the container: https://github.com/algorand/sandbox/blob/ef26221e9eb7141482234d061950e8a807f07a0c/images/algod/Dockerfile#L29

COPY . /tmp

3. investigate/modify for indexer as well.

4. Solution should parse the URL field value and switch based on the source.

Dependencies

None known.

Urgency

Nice to have.
