rename agentGateway to agentgateway

[npolshakova]

Leaving this open for a bit to get feedback if we want to still make this change. agentgateway is consistent with the dataplane naming, but camelcase is a common pattern with helm.

1. rename agentGateway to agentgateway for helm values and GatewayParmeters field (user facing)
2. rename agentGateway to agentgateway across the codebase for consistency (non user facing)
3. rename ADP/adp (agentgateway dataplane) to Agw/agw (non user facing)

Should we use Agw for internal type names and only agentgateway for user-facing APIs and docs?

[npolshakova]

Changed most of the internals here: f10c346

Ones I didn't change are:

• tests (TestAgentgatewayDeployment)
• deployer inputs (AgentgatewayClassName seems better in line with other classes ie. WaypointGatewayClassName)
• deployer helper functions/values (GetAgentgatewayValues, helm values on gateway.Agentgateway, etc. These are directly coming from the user inputs and translated to the deployer helm values, so keeping the sames similar makes more sense imo)

[Update] Changed ExtraAgentgatewayPlugins to ExtraAgwPlugins in: dc61cc0

pkg/agentgateway/plugins/traffic_plugin.go:1

• [nitpick] The log message should use consistent capitalization. Consider changing 'agentgateway' to 'Agentgateway' to match the type name used elsewhere in the codebase.

package plugins

pkg/agentgateway/plugins/traffic_plugin.go:1

• [nitpick] Consider using 'agentgateway' instead of 'Agentgateway' in these user-facing log messages for consistency with the lowercase naming convention used throughout the rest of the codebase.

The changelog needs to be updated to reflect the GatewayParameters API change
