Python dotenv usage

Context

The SDK is configured through the open_api.ini file. The file is parsing within base_client.py during instantiation of BaseClient descendants' instances.

There are use cases when it will be nice to have a possibility to configure the SDK by environment variables, for instance, when we use the SDK in CI/CD pipelines or provisioning scripts without usage of open_api.ini file.

Decision

• Use python-dotenv for config management

Scope

• Replace open_api.ini file by .env file (https://community.opengroup.org/osdu/platform/system/sdks/common-python-sdk/-/blob/master/osdu_api/base_client.py#L30);
• Change __init_ method of BaseClient class (https://community.opengroup.org/osdu/platform/system/sdks/common-python-sdk/-/blob/master/osdu_api/base_client.py#L49);
• Replace open_api.ini file for existing parsers (e.g. WITSML parser)

Optional:

• Add dynamic access to the parameters, i.e. remove explicit initialization of a instance properties and add dynamic access to any of them;
