Add solr search support to base marketplace application

Added dynamic Solr support to the Marketplace API using the 'q' query
string param and a service that consumes it. Currently, cache is
disabled on text searches to more quickly enable functionality. This
will be taken as technical debt and documented on GitHub.

 1. Create a copy of `./config/sample.secret.properties` named `secret.properties` in a location of your choosing on the system, with the config folder in the project root being default configured. If changed, keep this path as it is needed to start the environment later.
 1. Update `quarkus.datasource.password` to be the password for the MariaDB user in the newly created `secret.properties` file.
 1. Log in to the MariaDB instance and ensure that the database defined in the JDBC string exists. By default, the name of the database is `mpc_db`. This database can be created using the command `CREATE DATABASE mpc_db;`. 
+1. When using the Solr search engine, a couple of properties are needed to be added to the properties and secret.properties file. The first is the Solr host and core. The host property (`eclipse.solr.host`) should be the root URL to your Solr instance (e.g. http://localhost:8093/solr) to allow connections for search indexing. The core property (`eclipse.solr.core`) should be the name of the core that will store your indexes for marketplace. If a core does not exist yet, create one through the admin panel of the Solr server and update the core value if needed.
+1. To properly enable the core to work with this application, the configuration on the Solr server should be updated. Copy the contents of ./config/mpc_dev into your cores configuration folder. An example path for this folder is `/opt/solr/server/solr/marketplace`. This may change based on how the server is installed and configured. Ensure that these files match ownership of the other files in this location, otherwise the Solr core may not work as intended. 
 1. By default, this application binds to port 8090. If port 8090 is occupied by another service, the value of `quarkus.http.port` can be modified to designate a different port. 
 1. In order to protect endpoints for write operations, an introspection endpoint has been configured to validate OAuth tokens. This introspection endpoint should match the requirements set out by the OAuth group for such endpoints. The URL should be set in `quarkus.oauth2.introspection-url`.  
     * A property meant for development purposes has been added to this stack to bypass OAuth calls. If set, all calls will return as if authenticated as an admin. The property and value `eclipse.oauth.override=true` can be set in the `application.properties` file to enable this feature.

+   - set stored="false" for all fields possible (esp large fields) when you

+     value.
+   - set indexed="false" if you don't need to search on the field, but only
+     return the field as a result of searching on other indexed fields.
+   - remove all unneeded copyField statements
+   - for best index size and searching performance, set "index" to false
+     for all general text fields, use copyField to copy them to the
+     catchall "text" field, and use that for searching.

+      indexed: true if this field should be indexed (searchable or sortable)
+      stored: true if this field should be retrievable
+      docValues: true if this field should have doc values. Doc Values is
+        recommended (required, if you are using *Point fields) for faceting,
+        grouping, sorting and function queries. Doc Values will make the index
+        faster to load, more NRT-friendly and more memory-efficient. 
+        They are currently only supported by StrField, UUIDField, all

+        more information)
+      multiValued: true if this field may contain multiple values per document
+      omitNorms: (expert) set to true to omit the norms associated with
+        this field (this disables length normalization and index-time
+        boosting for the field, and saves some memory).  Only full-text
+        fields or fields that need an index-time boost need norms.
+        Norms are omitted for primitive (non-analyzed) types by default.
+      termVectors: [false] set to true to store the term vector for a
+        given field.
+        When using MoreLikeThis, fields used for similarity should be
+        stored for best performance.
+      termPositions: Store position information with the term vector.  
+        This will increase storage costs.
+      termOffsets: Store offset information with the term vector. This 
+        will increase storage costs.
+      required: The field is required.  It will throw an error if the

+
+       http://wiki.apache.org/solr/AnalysisRequestHandler
+
+       An analysis handler that provides a breakdown of the analysis

+       content stream with the following format:
+
+       <docs>
+         <doc>
+           <field name="id">1</field>

+         <doc>...</doc>
+         ...
+       </docs>
+
+    Note: Each document must contain a field which serves as the
+    unique key. This key is used in the returned response to associate
+    an analysis breakdown to the analyzed document.
+
+    Like the FieldAnalysisRequestHandler, this handler also supports
+    query analysis by sending either an "analysis.query" or "q"
+    request parameter that holds the query text to be analyzed. It
+    also supports the "analysis.showmatch" parameter which when set to
+    true, all field tokens that match the query tokens will be marked
