[strongSwan] TPM Owner password in strongswan IMC

Hi Vikas,

there is currently no provision to use a non-default password.
Putting the TPM owner password into strongswan.conf wouldn't make
any sense so some kind of password-prompting mechanism would have
to be built into the IMC. Or if the IMV would transmit the password
via an IF-M attribute to the IMC, this would give the IMC on the
client a chance to retrieve the password.

Best regards
