Update SecureSocket API of HTTP

[ldclakmal]

Description
Need to update SecureSocket API of ballerina/http module.

Currently, the HTTP ListenerSecureSocket and ClientSecureSocket APIs are as follows:

public type ListenerSecureSocket record {|
    crypto:TrustStore? trustStore = ();
    crypto:KeyStore? keyStore = ();
    string certFile = "";
    string keyFile = "";
    string keyPassword = "";
    string trustedCertFile = "";
    Protocols? protocol = ();
    ValidateCert? certValidation = ();
    string[] ciphers = ["TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256", "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256",
                        "TLS_DHE_RSA_WITH_AES_128_CBC_SHA256", "TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA",
                        "TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA", "TLS_DHE_RSA_WITH_AES_128_CBC_SHA",
                        "TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256", "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256",
                        "TLS_DHE_RSA_WITH_AES_128_GCM_SHA256"];
    string sslVerifyClient = "";
    boolean shareSession = true;
    int? handshakeTimeoutInSeconds = ();
    int? sessionTimeoutInSeconds = ();
    ListenerOcspStapling? ocspStapling = ();
|};

public type ClientSecureSocket record {|
    boolean disable = false;
    crypto:TrustStore? trustStore = ();
    crypto:KeyStore? keyStore = ();
    string certFile = "";
    string keyFile = "";
    string keyPassword = "";
    string trustedCertFile = "";
    Protocols? protocol = ();
    ValidateCert? certValidation = ();
    string[] ciphers = [];
    boolean verifyHostname = true;
    boolean shareSession = true;
    boolean ocspStapling = false;
    int handshakeTimeoutInSeconds?;
    int sessionTimeoutInSeconds?;
|};
