feat(cactus-plugin-ledger-connector-sawtooth): add new connector plugin

- Add new plugin for connecting with sawtooth ledgers.
- New connector is based on already existing sawtooth-socketio connector.
- Currently it supports only watchBlock and connector status endpoints.
- Add new connector to cactus-verifier-client
- Add integration tests in `cactus-test-plugin-ledger-connector-sawtooth`.

+# `@hyperledger/cactus-plugin-ledger-connector-sawtooth`
+
+This plugin provides `Cacti` a way to interact with Sawtooth networks. Using this we can perform:
+
+- Check plugin and sawtooth node status.
+- Monitor new blocks and transactions on the ledger.
+
+## Summary
+
+- [Getting Started](#getting-started)
+- [Usage](#usage)
+- [SawtoothApiClient](#sawtoothapiclient)
+- [Runing the tests](#running-the-tests)
+- [Contributing](#contributing)
+- [License](#license)
+- [Acknowledgments](#acknowledgments)
+
+## Getting Started
+
+Clone the git repository on your local machine. Follow these instructions that will get you a copy of the project up and running on
+your local machine for development and testing purposes.
+
+### Prerequisites
+
+In the root of the project to install the dependencies execute the command:
+
+```sh
+npm run configure
+```
+
+## Usage
+
+Before running the connector please ensure that Sawtooth node is running and that connector will have direct access to it. Access through a proxy is not supported yet (see https://sawtooth.hyperledger.org/docs/1.2/sysadmin_guide/rest_auth_proxy.html).
+To use this import public-api and create new **PluginLedgerConnectorSawtooth**.
+
+```typescript
+const connector = new PluginLedgerConnectorSawtooth({
+  instanceId: uuidV4(),
+  logLevel: testLogLevel,
+  sawtoothRestApiEndpoint: ledgerRestApi,
+  watchBlocksPollTime,
+});
+```
+
+You can make calls through the connector to the plugin API:
+
+```typescript
+async getStatus(): Promise<StatusResponseV1>
+```
+
+Please note that `deployContract()` and `transact()`, although available to call, **are not implemented and will throw error on runtime!**
+
+## SawtoothApiClient
+
+All connector API endpoints are defined in [open-api specification](./src/main/json/openapi.json). You can use [SawtoothApiClient](./src/main/typescript/api-client) to call remote sawtooth connector functions. It also contain additional utility functions to ease integration.
+
+### REST Functions
+
+See [DefaultApi](./src/main/typescript/generated/openapi/typescript-axios/api.ts) for up-to-date listing of supported endpoints.
+
+- getStatusV1
+
+### Asynchronous Functions (socket.io)
+
+- watchBlocksV1
+
+## Running the tests
+
+To check that all has been installed correctly and that the plugin has no errors run jest test suites.
+
+- Run this command at the project's root:
+
+```sh
+npx jest cactus-plugin-ledger-connector-sawtooth
+```
+
+### Building/running the container image locally
+
+In the Cactus project root say:
+
+```sh
+DOCKER_BUILDKIT=1 docker build -f ./packages/cactus-plugin-ledger-connector-sawtooth/Dockerfile . -t cplcb
+```
+
+Build with a specific version of the npm package:
+
+```sh
+DOCKER_BUILDKIT=1 docker build --build-arg NPM_PKG_VERSION=0.4.1 -f ./packages/cactus-plugin-ledger-connector-sawtooth/Dockerfile . -t cplcb
+```
+
+#### Running the container
+
+Launch container with plugin configuration as an **environment variable**:
+
+```sh
+docker run \
+  --rm \
+  --publish 3000:3000 \
+  --publish 4000:4000 \
+  --env AUTHORIZATION_PROTOCOL='NONE' \
+  --env AUTHORIZATION_CONFIG_JSON='{}' \
+  --env PLUGINS='[{"packageName": "@hyperledger/cactus-plugin-ledger-connector-sawtooth", "type": "org.hyperledger.cactus.plugin_import_type.LOCAL", "action": "org.hyperledger.cactus.plugin_import_action.INSTALL",  "options": {"rpcApiHttpHost": "http://localhost:8545", "instanceId": "some-unique-sawtooth-connector-instance-id"}}]' \
+  cplcb
+```
+
+Launch container with plugin configuration as a **CLI argument**:
+
+```sh
+docker run \
+  --rm \
+  --publish 3000:3000 \
+   --publish 4000:4000 \
+  cplcb \
+    ./node_modules/@hyperledger/cactus-cmd-api-server/dist/lib/main/typescript/cmd/cactus-api.js \
+    --authorization-protocol='NONE' \
+    --authorization-config-json='{}' \
+    --plugins='[{"packageName": "@hyperledger/cactus-plugin-ledger-connector-sawtooth", "type": "org.hyperledger.cactus.plugin_import_type.LOCAL", "action": "org.hyperledger.cactus.plugin_import_action.INSTALL",  "options": {"rpcApiHttpHost": "http://localhost:8545", "instanceId": "some-unique-sawtooth-connector-instance-id"}}]'
+```
+
+Launch container with **configuration file** mounted from host machine:
+
+```sh
+
+echo '{"authorizationProtocol":"NONE","authorizationConfigJson":{},"plugins":[{"packageName":"@hyperledger/cactus-plugin-ledger-connector-sawtooth","type":"org.hyperledger.cactus.plugin_import_type.LOCAL","action":"org.hyperledger.cactus.plugin_import_action.INSTALL","options":{"rpcApiHttpHost":"http://localhost:8545","instanceId":"some-unique-sawtooth-connector-instance-id"}}]}' > cactus.json
+
+docker run \
+  --rm \
+  --publish 3000:3000 \
+  --publish 4000:4000 \
+  --mount type=bind,source="$(pwd)"/cactus.json,target=/cactus.json \
+  cplcb \
+    ./node_modules/@hyperledger/cactus-cmd-api-server/dist/lib/main/typescript/cmd/cactus-api.js \
+    --config-file=/cactus.json
+```

+- This plugin uses Sawtooth REST API OpenAPI specification from https://sawtooth.hyperledger.org/docs/1.2/rest_api/openapi/. We did some changes to the original spec in order to simplify request handling (e.g. change type, mark fields as requried, etc...)
